I am reposting this with the adjustments that I made. Turned out great and makes a lot. We use ground turkey in most of our recipes, and the turkey sausage makes a nice substitution for pepperoni. I add the carrots to boost the veggie impact, or you can use pureed sweet potatoes instead. Feel free to use whatever pizza toppings you like!
1 lb ground turkey, browned and drained
1 bag whole wheat egg noodles, cooked al dente (not quite done)
2+ cups mozzarella cheese
1 cup finely chopped or pureed carrots
1 cup smoked turkey sausage, sliced
1 extra large jar spaghetti sauce (3lb size) or two regular-sized jars
1 T minced garlic
Italian seasoning to taste
And other pizza toppings if available: chopped onions, peppers, mushrooms, etc.
Brown the ground turkey (w/ onions, peppers, and garlic, if using). Add carrots for last 3 mintues of cooking time, then add half the sauce in with the meat. Layer meat/sauce, noodles, cheese, turkey sausage, and repeat layers until crockpot is full, ending with a layer of sauce & the Italian seasoning. Cook on low all day. Shortly before serving, add more cheese to the top and allow it to melt.
