Hi and welcome! This has been a pretty quiet team, I just joined myself a few months ago.
Anyway I love to freeze meals in advance. You can find tons of great books on the subject. I recomend you start with your family's favorites and decide if you can freeze them. When I set out to freeze something I normally will cook something off my regular meal, double it, serve one meal and freeze the second one.
In my freezer I always have frozen marinara or meat sauce, meatballs, pizza dough, a few favorite casseroles, lasagna, cookie dough, chili, meats frozen in marinades, rice and soups.
