Don't judge my picture. Just be glad that there is one and I didn't steal it from some other blog! :) Also, the original recipe calls for dropping dollops of the ricotta on top. In the end we ended up mixing it into the pasta to eat it. So I would just go ahead and do it while cooking.
Source: ??? I printed this off a while ago and don't know where it came from :(
3 (14.5 oz) cans whole peeled tomatoes
1 (8 oz) can tomato sauce
1 T olive oil
1 med onion, minced
1 tsp Salt
3 medium garlic cloves, minced
1/8 tsp red pepper flakes
1 T dried Basil
1/2 T dried Oregano (I just used Italian Seasoning)
1 lb ground beef
12 lasagna noodles, broken into 1 in pieces
1 cup shredded mozzarella
1/2 cup grated Parmesan (I used shredded Italian blend)
3/4 cup ricotta cheese
Pulse the tomatoes with the juice in a food processor until there are no large pieces.
Heat the oil in a large nonstick skillet (I used a 12", if you have bigger use it) on medium heat. Add the onion and salt. Cook about 5 minutes. Stir in garlic and red pepper, cook about 30 seconds. Add the ground beef and cook until browned.
Scatter the lasagna noodles on top. Mix together tomato sauces, basil, and oregano. Pour into skillet. Mix together. Cover and cook about 20 minutes. Watch that it doesn't stick and stir frequently.
Turn off the heat. Stir in half of mozzarella and Parmesan cheeses. Mix in Ricotta cheese. Sprinkle the remaining cheese on top and cover. Let sit about 5 minutes, until cheese melts. Serve!
