I think mini muffins are great for bentos. They are tiny, easy and fast to make, freeze beautifully, and defrost naturally by lunchtime if you take them out of the freezer in the morning. They are handy snacks to eat when your energy is running low but you don't have time to stop and eat properly, and are also great accompaniments to a soup or salad.

Here are two savory muffin recipes that also happen to be vegan.

Greenhouse grown peppers are available year round, but summer is when peppers are really in season. I picked up a bushel load of colorful hot and sweet peppers at a market last week, and some of them turned into this item which is great for bento.

It couldn't be easier to make, but does take a little time. A mixture of mildly hot chili peppers and sweet peppers are briefly stir fried in sesame oil, then simmered for about half an hour or more. The peppers are falling-apart soft, spicy, sweet and salty. It's great to tuck into the corner of a bento box, and, well drained of the cooking liquid, also makes a great and unusual filling for onigiri (rice balls).

My grandmother used to make this kind of 'cooked to death' or until very limp (kuta-kuta ni) vegetable dish quite a bit. It's a great way to reduce a big pile of vegetables to a manageable eating amount. This method works well with green beans too. I think it's rather similar to the way some vegetables such as greens are cooked for a long time in American Southern cooking. I'm no nutrionist, but you do eat all of the 'cooking liquor' alongside the vegetables, so nutrition loss may not be so bad, though raw-food advocates may shudder.

The key here is the selection of peppers. The spicy chili pepppers should only be mildly spicy. In Japan you would use shishito peppers. Here I used a variety from Italy that I'm not sure of the variety name of, but it is similarly thin-walled and mild enough not to burn my mouth. Jalapeños or anchos might be good choices too. For the sweet peppers, I used the long red peppers that are called banana peppers, Hungarian peppers or paprikas, depending on who is selling them and where.

Previously I showed you how to make instant miso soup balls to which you just add boiling water to make a hot cup or bowl of soup. But even I don't want miso soup all the time. Instant soup mixes are an option, but they are usually rather salty, and don't contain a lot in terms of nutrients. So I set about experimenting with making my own instant soup concentrate. After some trial and error, here's a formula for a Mediterranean tasting vegetable soup concentrate that works pretty well. It does take some mostly unattended time to cook down, so it's a good project to do over the weekend to stock up for upcoming bento lunches.

There are three very commonly used Japanese egg recipes. One is _tamagoyaki_ or atsuyaki tamago_ (and its variant, _dashimaki tamago), a rolled omelette. Another is _usuyaki tamago_, a very thin omelette which is used as a wrapper or shredded and used as a topping. Ther third is iri tamago, finely scrambled eggs that are used quite a lot as a topping. It's here because it's such a handy ingredient for bento. If you think you need a bit of color and protein, there's no faster egg dish you can make.

This is a sort of short-term storage staple. It only keeps in the refrigerator for about 3 or 4 days, but you can make them at any time and they are handy for filling a corner of a bento box.

There are many more complicated recipes for tea eggs, a traditional Chinese recipe. The boiled eggs are usually meant to be kept in the tea-based marinade with their shells on, carefully cracked all around so that a lovely marble pattern is revealed when the eggs are peeled.

My method is way simpler, and is motivated by the fact that I don't really want to be fiddling around with peeling eggs in the morning. Since the eggs are totally peeled, the marinade will penetrate it faster and deeper, so you can start using them just an hour after you've put them in the liquid if you like.

This colorful, healthy yet tasty all-vegetable mixture is a great refrigerator staple for using in your bentos, and is very adaptable. Depending on the flavors you can add later, it can taste Italian, Japanese, Chinese, or whatever suits your needs.

It's a mixture of thinly siiced onions, sweet peppers and a little garlic, sautéed over a fairly low heat until it's quite limp. It's only seasoned with salt, so that it's fairly neutral. You can then turn it more Mediterranean by adding some basil and oregano for example, or Japanese by adding soy sauce, or add some oyster sauce.

Noritama is one of the most popular flavors of furikake available commercially. Nori means the seaweed that's used as a sushi roll or onigiri wrapper, and tama is short for tamago, or egg. The base, which gives the most flavor to the furikake, is bonito flakes or katsuobushi.

Surprisingly perhaps, noritama is one of the more fiddly furikake to make at home, though it's by no means difficult. But I like to make it occasionally anyway becase I find commercial noritama to be a bit too salty. This version is lower on salt, so you can pile it on your rice if you want to. Naturally it's free of any preservatives, MSG, or what have you. It's also a lot cheaper than the commercial versions, even if you have to pay premium prices for the bonito flakes and nori as I do.

Kombu, the leathery seaweed that is used to make dashi stock, is packed full of umami. A traditional way to prepare it is as shiokombu (salty kombu) or kombu no tsukudani. Tsukudani is a method of cooking something with soy sauce, sake and/or mirin, and sugar until it's very dark, quite salty and sweet too. It's a preserving method, since the salt and sugar greatly increase the keeping qualities of the food.

Kombu no tsukudani can be tucked into the corner of a bento box to add a little variety. It's also a good onigiri filling. Properly made and stored in the refrigerator, it keeps almost forever.
