Meals That Reheat Well

Does he bring home any meat? You can make stew.
Meat, carrots, potatoes, onions....
Potato soup, split pea soup, lentil soup, minnestrone soup....
Spaghetti reheats well if they add a little water to the pan so it doesn't stick.
My brother in law hunts and they rough it, to be sure, but they cook all their own stuff. They take eggs, bread, stuff to make sandwiches...
Oh....they bake potatoes ahead of time and take them to slice up and fry.
He has it down. I'll have to ask him. I know he takes fish from the freezer and things like that. They don't even stay in a cabin.
They're crazy if you ask me, but my sister doesn't cook for them. And they're in the middle of nowhere so they can't get anything they don't take.
I hope you get some great suggestions.

Spaghetti tossed in the sauce reheats well but use Angel hair pasta instead. Goulash is great depending on the noodle, anything too thick turns to mush, try a small elbow noodle. I do mine simple message me if you care for the recipe. Chicken soup with some veggies or anything with a broth really heats up well. Pizza boats would be easy for them to put together and toast up on the wood burning stove. Do the others wives help?

Red Beans and Rice with a large ham bone. Add water when reheating.

what about a vegetable beef soup or stew? pot roast..just leave the juice in it?

A hearty beef stew would reheat well.

IF you do goulash, then make sure the noodles are just slightly soft. Don't cook them as long the first time.
