Brown hamburger and sausage until no longer pink; drain. Add spaghetti sauce to meat and simmer on low for 10 minutes.
Preheat broiler. Butter english muffins and broil until golden brown.(I use the spray butter, it's much faster.) Turn oven down to 350° F.
Top each muffin with processed cheese. Spoon on meat mixture and then top with mozzarella. Bake until cheese is melted, 5 to 10 minutes.
To cook frozen pizzas, bake at 350° F for 15 minutes or until heated through.
