Second the lasagna.
Beef stew also freezes well. Chunk veggies on the thicker side so they don't overcook when you reheat.
Chicken soup. Add small pastas after you defrost
Or make a homemade tomato sauce/gravy (with or without meatballs) and freeze that. Then defrost and make pasta to go with it.
The iron skillet gets very hot so when I heat it up (electric stove), I turn it on high at first, then add oil/bacon grease and turn it down to med or med/low.
