Get to know your crock pot. They are life savers on busy days. Also, can you double your recipes and freeze half for busy days? We like to do things like taco salads, homemade chipolte, soups, stews (once the weather changes and we have cooler weather), salads (with grilled or leftover chicken for protein), ravioli (not the canned kind, but the frozen type from Costco-but it has cheese in it), spag with meat sauce on what we call "fast food" days. Those are our fast foods. LOL But, you can put a roast, or a whole chicken in the crockpot with some vegies and let it go all day also.
Can't help you with the lunches. We homeschool. After seeing all the posts about homework, I'm more thankful than ever that we homeschool. My children never have homework to do after school hours. I can't imagine!
