All the luscious, layered goodness of traditional lasagna but easier and cheesier with premade ravioli and a homemade meat sauce that simmers in the slow cooker until the flavors are perfectly melded.
Add the tomatoes, tomato sauce, water, oregano, basil, parsley, garlic powder, onion powder, salt, pepper, and honey to the ground beef. Stir to combine. Cook over medium-high heat for 5 to 10 minutes or until it just starts to boil.
Spray the inside of the slow cooker with non-stick cooking spray. Ladle a scoop of the meat sauce into the slow cooker. Add a layer of ravioli, then ladle more meat sauce over the ravioli, layer four slices of provolone, and then sprinkle some mozzarella over the provolone.
Repeat each layer until all the ingredients are used, topping everything off with a final layer of cheese.
Place the lid on the slow cooker. Cook on low for 4 hours or on high for 2-2 1/2 hours, or until a thermometer inserted through the ravioli reaches 165 degrees.
