English muffins (split)
Mozzarella, American cheese, sliced (or favorite) or shredded
Pizza sauce
Mushrooms (canned or fresh, sliced)
Olives, sliced
Onion, chopped
And/or toppings of choice
Meat of choice (sliced or crumbled)

We like to lightly toast the muffin halves. Spread pizza sauce on top. Add toppings of choice. Sprinkle or lay cheese on top. Place halves on microwavable plate and heat until cheese is melted. (Watch carefully as it depends on your microwave and how many you are heating at one time.)
