I HAVE MADE ADJUSTMENTS TO THIS RECIPE. I love a good Baked Rigatoni and as much as I love baked cheese, I find that when cooked in the oven the meal turns out dry and I wanted to make a Rigatoni that wasn't dry and the cheese was melted throughout. I also don't like too much sauce and prefer a nice balance, so I make this version. I did this by starting the meal on the stove and finishing in the crockpot and it tasted so good. The smell made everyone hungry. It was a big hit. See end of the recipe for more ideas using the basic easy tasty sauce. I found that Newman's Own sausage and pepper sauce was the perfect compliment to this dish. Serve with a salad and garlic bread if you wish. If you choose to use organic grass fed ground beef 1 lb. is plenty. Nice lean bulk Italian sausage and you getting all meat and barely any juices from the meat so your saving money by not having to buy extra meat. The flavor is incredible.
