Since you asked, here are instructions to make Crock Pot Lasagna. I've only tried it once, and our creation was based on the recipe in Make it Fast, Cook it Slow by Stephanie O'Dea. It turned out great, and the whole house smelled like an Italian restaurant!
A box of 10 or so noodles (I used brown rice noodles, but you could use any kind)
25 oz. of tomato sauce (we used a store-bought spaghetti sauce)
Veggies or meat (We're not big meat-eaters, so we used eggplant, onion, mushrooms and zucchini)
Riccota cheese (I used about half of one of the smaller-sized containers)
First, saute the vegetables lightly (and brown meat if you're using it). Add the sauce to the veggies and/or meat to make a nice chunky sauce. Assemble the lasagna: Start with a layer of sauce, then add noodles (uncooked!) and ricotta. Repeat. End with sauce, and sprinkle mozarella on top. We cooked our for about 3 1/2 hours on High and it was perfect. So easy!
