Honey...I was raised by a Native American mother, I know how to cook in bulk on the cheap!
-Awesome chili gets better as it sits in the fridge...a huge pot will last you at least a week. It's tasty, economical, and healthful:
In a huge pot:
1. Stir fry diced onion and garlic in some olive oil until they turn golden brown.
2. If you want meat, add now. I occasionally use ground turkey breast.
Add your choice of veggies, my faves include: chayote squash, green beans, and a can of corn. Add a small can diced (or dice your own chili peppers-mild to spicy, whatever you prefer).
3. Add beans. If you really want to save money, buy dried beans and boil them yourself, and don't drain. If you're adding canned beans, don't drain either, just dump it all in the pot. I use black and red beans, sometimes navy beans and chickpeas too.
4. Add one can diced tomato, or a couple of large freshly diced tomatoes, and one can tomato paste.
5. Add a splash of vinegar and season to taste using traditional Mexican seasonings (you can even buy "Mexican Seasoning" in many spice sections.
-Succotash (thestrangequark's version)
In case you don't know, succotash is a traditional Native American food cooked in some variation by most Indian tribes across N. America. Like fry bread, it's a classic. There are many variations, the only rule being it must have corn and lima beans. This is a great meal for a single health-minded person on a budget, because pretty much all the ingredients can be bought frozen, and it's quick and easy to prepare. This means you don't have to cook one huge dish that you'll be eating all week, while still not worrying about your food going bad:
1. Sautee chopped onion in 1 tbsp olive oil. Garlic too if you like.
2. Add some frozen corn, lima beans, green beans, green peas, carrots, broccoli, whatever frozen veg you like. I also like to throw in a few little grape tomatoes.
3. Add a can of chickpeas.
4. To cut on calories and add flavor, instead of adding more olive oil to keep things moist, try cooking in chicken brothI'd recommend Better than Bullion.
I can post more recipes too, if you like.
