Lasagna
This version of lasagna is really unbeatable, with lots of mushrooms, spinach, and cheese. Use no-cook (or no-boil) lasagna noodles so you don’t have to cook them beforehand—they absorb the liquid in the filling and cook as the lasagna bakes. If you’re having people over, you can assemble it in advance and keep it in the fridge until you’re ready bake it. Serve it with a big salad and garlic bread, and you can practically feed your whole neighborhood.
