I love having a freezer full of food! I'm a vegetarian so I freeze meatless meals. Besides lots of soups, bean dishes (like split pea soup and chilis) I've had success freezing: cooked frittatas, crustless quiche, various homemade veggie burgers, enchiladas (layered like lasagne), burritoes, stuffed pastas (manicotti, shells), twice baked potatoes, and vegetable risottos.
I also freeze all kinds of muffins, since I'm the only one in the house that eats muffins and I can't eat 12-18 that fast!! I've even frozen cooked biscuits to eat by dunking in thick soups.
Let me know if you are interested in some vegetarian meals and I can dig up a few recipes!
