Cook ground beef and pork pan sausage together in a large skillet until browned. Drain off the oil. Add the jar of Ragu spaghetti sauce to meat mixture and heat.
While my meat mixture is browning, I cook my lasagna noodles (according to instructions on the box) and drain.
Cover the bottom of a 9 x 12 pan with half of the noodles. Pour half the meat mixture over the noodles. Add half of the mozarella & cheddar cheese. Layer remaining noodles, meat mixture, and top with all remaining cheese. Bake for about 30 minutes. I usually make garlic bread, salad, and iced tea to go with it.
