I don't have a written plan, but when I cook a casserole or meat, I always make enough for another meal. If it's grilled chicken breasts, I use the leftovers in a hearty salad the next evening. Spaghetti sauce, BBQ pork butt, meat loaf. Always more than one feeding. Sometimes it waits for an extra day before it gets eaten. We may get take-out once a week, and I cook or warm up left overs the other days. But no, no meal plan.
