Once muffins are cool enough to touch, spoon pizza sauce over top of english muffins.
Add any toppings and sprinkle cheese on top.
Cover all of the english muffins with toppings. Place in a 375 degree oven for 8-12 minutes, or until cheese is melted. Carefully remove from oven. Enjoy!
*Disclaimer: do not allow children to place/remove items from the oven. This can result in serious burns. Allow english muffins to cool entirely before letting children add toppings and cheese. The pizzas will be very hot when removed from the oven, so be cautious when serving to small children.
