preheat oven to 350°

Brown hamburger meat

dice bell peppers and onion and mince garlic, then sautee in large saucepan until soft. Add both jars of spaghetti sauce, both cans of diced tomatoes and hamburger. let simmer for 30 minutes on medium-low heat.

pour a thin layer of spaghetti sauce mixture into the bottom of 13x9 casserole dish

put one layer of lasagna noodles over the sauce

layer as follows: (from bottom to top): sauce, lasagna noodles, spaghetti sauce mixture, ricotta cheese, shredded mozzarella, thin sauce layer, then repeat.

Make sure there is sauce on both sides of pasta, then finish with thick layer of mozzarella. To keep cheese from sticking to the foil I insert toothpicks between the pasta (the liquid frkm the sauce helps cook the pasta) and make a sort of tent

cover with aluminum foil

bake at 350° for 45 minutes or until pasta is Al dente
