Oh, I totally get that approach. I have a large household, myself, husband, two kids, and two roommates. When we make a meal, we make enough for all of us, and hopefully enough to have leftovers for up to a week.
However, right now I'm dieting, which means no huge amazing meals full of carbs and sugars. So right now my dinner consists of: sautéed chicken, onions, mushrooms, with chicken bouillon, chicken stock, cumin, thai chili peppers, and some other stuff my husband throws in for flavor, mixed with jasmine rice. If you like things spicy, its delicious!
Also, I make homemade hummus for my lunches. Yummy!
