Beans and rice freeze really well. Bren and I make a whole bag of rice and a whole bag of black beans and then mix them and separate enough for single meals in plastic ziplock bags. Then when you're ready to eat, just add a few tablespoons of water and reheat on the stove or microwave. You can add different things to spice it up and make it different each night. I use chicken, cheese, tomatoes, onions, salsa, spices (cumin and cilantro are great for this)...or even put it in a tortilla to make a burrito. Try different combinations of those things. There are a million and one ways to eat beans and rice. It's cheap and even healthy too!
