Lazy Lasagna - cooking recipe

Ingredients

1 1 lb pasta shells or 1 lb macaroni
1 lb ground beef or 1 lb bulk Italian sausage, browned and drained
1 lb ricotta cheese
1 lb pre-shredded mozzarella cheese
1/2 cup parmesan cheese
1 -2 quart spaghetti sauce (I prefer Classico)
olive oil

Preparation

Cook pasta a bit less than fully done.
Grease a 9x13 pan with olive oil.
Layer 1/2 the amount each of pasta, ground beef, ricotta, parmesan, spaghetti sauce, and mozzarella in that order.
Repeat except for the mozzarella.
Draw a wooden spoon through the layers in an S-shaped pattern to mesh the layers without actually stirring them together.
Top with the remaining mozzarella.
Bake at 350F for 30-45 minutes or until the cheese is as brown as you like it and everything is bubbling hot.
Note -- steamed and drained zucchini or very well-drained, frozen spinach is a good addition.
Note -- Can substitute ground turkey or chunks of cooked chicken/turkey for the ground beef if desired.
