Hey RootsNwings
When I've done some freezing of meals, I find that most pasta recipes freeze well (Spaghetti, Mac & Cheese, Lasagna, Tuna Casserole, etc...). Broth-based Soups freeze well also. If your family likes Breakfast for dinner, you can make a large number of Waffles and Pancakes and freeze them, to re-heat in the Microwave or Toaster.
If you want to break it down even simpler, just cook the pasta, package it and freeze. Thaw in the refrigerator the night before and re-heat in the microwave with your favorite jarred/canned sauce poured over, then toss.
(Quick sauce recipe: Butter, Olive Oil, Chopped Garlic, salt and pepper - all to taste - this can be pre-cooked packaged and frozen until needed - heat thru on the stove. Toss thru re-heated pasta - fetuccini, linguini, angel hair, egg noodles - Sprinkle with parmesan. A quick light pasta side)
I find that if I package into single servings they re-heat up better. Also, you can lightly flavor your pastas after cooking and before freezing. I've been known to flavor spaghetti with a little teriyaki sauce and soy. When I've re-heated it, I've served it with Stir-Fry Vegetables (from the Freezer section at the store) and Lightly Seasoned Chicken Breasts (which can also be prepared and pre-cooked).
Meatloaf can be pre-made and frozen (uncooked and cooked). Place in fridge the night before to thaw and continue heating as needed (following the rest of the recipe if at the uncooked stage ).
Hamburger patties can be seasoned and premade (uncooked) and frozen, then on the night to be cooked, place on a rack in a sheet pan and bake at 350 F for 30 to 35 minutes. Top with cheese and serve on buns with your favorite condiments and sides.
As for the chicken, if you place chicken breasts in freezer bags with a marinade (any store-bought bottled dressing like Balsamic Viniagrette, Italian or maybe Vidalia Onion Dressing will do), you may thaw in fridge the night before and place on a baking sheet the same way as the burgers and bake the same way.
One thing that will always help others, if you are leaving these meals for others to cook, would be to tape simple heating instructions on the sides of each package.
If there is anything else I can do to help, let me know. I just got a Do-ahead Cook Book from a local Used Book Store and might be able to look up some specific recipes. Hope my current suggestions help.
