This is a good start....will smell great simmering as low as you can set it, stir everytime you pass thru the kitchen, hopefully at least every 15 mins! The Old Farmers Wife was working around the house so passed through the kitchen often. Don't worry....
Take 1 pound of hamburger
Add 1/2 cup bread crumbs
1/4 cup parmesan cheese
Few shakes of mixed Italian
Some minced or diced onion
Salt/pepper to taste
Mix well, form balls to preferred size, fry or bake, then add to sauce.
And the Sausage, cut mild or hot to 3-4" lengths
Saute until done. Prick in several places to release the grease. Some modern sausage is so fat free you might want to add a bit of oil to pan, it will cook better.
Add to sauce
