Who has time for the labor-intensive layering required to make and bake a lasagna? Why not just scrap the oven entirely and make an easy, low-cost pasta pie? Start by boiling some lasagna noodles; then toss in fried mushrooms, frozen spinach or whatever veggies you happen to have on hand. Add a can of diced tomatoes, then top with ricotta or Parmesan cheese. If you want to add meat, stir in some leftover sausage, ground beef or turkey to complete this delicious family meal. Of course, if you'd prefer your lasagna a little more baked, try this simple lazy lasagna recipe.
