I agree, try the crockpot. Are you familiar with the lady who did a crockpot recipe every day for a year? I use a lot of her ideas and they also happen to be pretty budget-friendly. Also with a crockpot, you can easily double the recipe and freeze a portion to reheat the following week.

My favorite budget-friendly family meal is rice and beans. Cup of rice, can of black or pinto beans, two cups water, cook. Sprinkle shredded cheddar or a mexican cheese blend on before serving. You can serve it on its own or in taco shells or soft tortillas. It's (relatively) healthy, my kids love it and it also reheats well.
