In a large and deep skillet over medium heat add the Italian sausage, ground, beef, and onion and cook till the meat is browned and cooked through. Drain any grease from the pan, add the garlic and cook one additional minute.
Add the pasta sauce, water, red pepper flakes, basil, and Italian seasoning, and stir to combine.
Add the broken lasagna noodle pieces and stir. Increase the heat to medium high. Once it comes to a boil, cover with a lid and reduce the heat to low to keep it at a gentle simmer.
Stir occasionally until the noodles are tender. If any noodles start to stick together during this time, separate them so they don’t continue to cook together. The noodles should be done in about 10-15 minutes. If you need to, add a bit more water if your sauce becomes too dry before the noodles are cooked.
While your noodles cook, mix the ricotta cheese, parmesan cheese, salt, and pepper.
Once your noodles are cooked to al dente, dollop the cheese mixture over the top and sprinkle the mozzarella cheese on top. Cover with a lid and cook for a few more minutes till the cheese is melty or alternatively if you are using an oven-safe skillet you can broil, uncovered till the cheese is melty and starts to brown.
Sprinkle with parsley or basil if desired.
Serve while still hot.
