Break up sausage and beef in pan until all the meat is in small pieces. Brown and let cool.
Add ricotta and Parmesan cheeses, parsley and eggs and stir until the whole thing is mixed. Add breadcrumbs, raisins. Add sugar, salt and pepper to taste and mix again. I like it a little on the sweet side.
Grease oven bowl with cooking spray, place mixture in bowl and put in 350° oven for about 45 minutes, or until it appears cooked through.
