Have a few things on hand for a meal in a pinch so that you don't fell like you absolutely HAVE to call for takeout or go out to eat. Don't go overboard with this, but consider it and here are a few things that I keep on hand just in case a recipe goes bad or I need to have dinner ready in 15 minutes.
Tuna melts - tuna, cheese, mayo, bread, skillet (takes about 8 minutes to make)
Pizza - refrigerated croissant dough, tomato sauce, cheese, whatever topping available (15 min.)
Pesto Pasta - noodles (usually penne), pesto sauce (preprepared, multi-use size) (15 minutes)
Salad or Chef Salad - salad fixin's, deli ham, turkey and cheese if going Chef style (10 minutes)
These are my fall back recipes that are quick, satisfying, low stress and inexpensive.
