Welcome back,
Here is a list of ideas, https://www.ditchthecarbs.com/9-bes...-freezer-meals/
I freeze similar recipes, but with meatloaf, prefer to freeze it uncooked in an aluminum loaf pan, defrost, and then bake it right before dinner. All manner of stews, like beef bourguignon work https://www.dietdoctor.com/recipes/...auliflower-mash (check this site for more recipes) The leftovers can be frozen, and reheated quickly in the stove top or in microwave with a defrost, then reheat cycle. Egg based casseroles don’t do so well in freezer, but do last quite a few days in the fridge and I don’t mind repeating those meals until gone.
All the best,
