Homemade tomato sauce*
*Sauce:
Combine 1 lg. can diced tomatoes, cooked ground beef, 2 T. Italian seasoning, combine and simmer on stove while making pasta. (this is where I add my secret ingredient, not listed in this recipe.)

In large skillet, brown meat. Cook jumbo shells and rinse thoroughly until cool to touch. Combine ricotta, spinach, garlic, Parmesan and 1 c. mozzarella and mix thoroughly. Stuff shells. While boiling/stuffing pasta, make your sauce. Simmer burger & tomatoes. Cover bottom of pan with meat sauce arranging shells in single layer. Top with sauce, and Parmesan & remaining mozzarella cheese. Bake in 350 degrees oven until heated through, about 30 minutes. Serve w/ garlic bread.
 
Tip: I use a disposable pan. Easy clean-up!
