OP, check out the NY Times Dining section online - they should still have all their articles from this past Wednesday. Their theme this week was cooking at home more. The article that I thought was particularly useful was one that said "invest either time or work, but not both" -- here it is:

A few things that you may find helpful: 1) Make 1 or 2 big one-pot dishes on the weekend that will cover you for a couple of days. Soups or stews are great. Pasta or rice casseroles too (chili mac, tuna noodle, jambalaya, shepherd's pie, etc.). The crock pot is great for this. 2) Once a week, before you do your big grocery shopping, plan out your menus for the week. Write down on a big board what dinner is going to be so everyone in the family knows what to expect. 3) Another PP suggested this and I echo it: Breakfast for Dinner. Meaning toast, eggs, bacon, or pancakes and fruit. Quick and easy. This is what my family has every Friday. 4) Always have supplies for "fail safe" dinners in the pantry and fridge. E.g. tacos or quesadillas are what we do in our family for last-minute dinners, because we always have canned beans, tortillas, salsa, cheese, etc. Good luck!
