Reddit mentions of 500 Soups: The Only Soup Compendium You'll Ever Need (500 Series Cookbooks)

I'd recommend lasagna, make a whole tray and it will last you many meals and freezes well. You can find basic recipes on the back of lasagna noodle boxes. Add spinach, squash, zucchini, etc to make it healthier. I know people who use cottage cheese instead of ricotta which makes it cheaper and healthier (and they swear it still tastes as good).

Personally, I make a lot of daal makhani and I'll eat it over the course of a week and it still tastes amazing. However the ingredients may be tricky to find if you don't have a good Indian store nearby/are a cooking newbie. Unfortunately I can't give you a recipe as I don't know the English names for several key ingredients. The internet is your friend, however I'd suggest leaving out any milk or cream, it'll probably make it spoil faster and (in my opinion) does not taste any better.

Thai green curry and red curry are actually surprisingly simple to make. They may not last a whole week, but 3-5 days at least. You can find curry paste at your local Asian grocery store. Regular grocery stores carry it, too, but it's wayyy more expensive and less tasty. Pan fry garlic and onions in oil, add the curry paste and coconut milk. Make it a soup by adding a cup or two of veggie or chicken broth. Add your favorite veggies (my faves are green beans, bell peppers, broccoli and onions) + protein and ta da! Delicious food for all and easy to make in bulk.

As far as soups go, I have a book called 500 Soups. It's got a pretty good variety and has a lot of meal-in-a-bowl type dishes and I think a whole section on healthy soups as well.

Lastly, another Indian dish... palak paneer. It requires no fancy spices and is super healthy. You can substitute chicken for the paneer if you don't want to go to an Indian store. If you do that, I'd recommend simmering the chicken for a bit in the spinach mixture after you puree it so it soaks up the flavors more. You can eat it with rice or wrap it up in a tortilla like a burrito. Should last you most of a week in the fridge.

I bought a book called 500 best soups. It's not this exact one, but something like this: http://www.amazon.com/500-Soups-Compendium-Cooking-Sellers/dp/1569069786/ref=sr_1_1?ie=UTF8&qid=1319506108&sr=8-1 . This shit is delicious. Really, really delicious. Plus, you'll learn how to cook. Also, it's hard to make great soup, but it's also hard to make terrible soup.
