Preheat oven to 350F
Split English Muffins in half with fork or by hand, lay them on baking sheet and bake for 5-7 minutes for them to get a little crispy, but before they start turning brown - keep an eye on them.
While english muffins are crisping up, mix your garlic herb butter by taking melted butter and adding in onion powder, garlic powder, italian herbs, and minced garlic - mix well, then brush onto crisp English Muffin halves.
Build the pizza by putting the garlic herb butter on the English Muffin, then add shredded mozzarella cheese, pizza seasoning, and your toppings - pepperoni in this case.
Place back in oven and bake for 7-10 minutes until cheese is nice and melted and pepperonis start to crisp up.
Remove from oven and let cool for 5 minutes.
Serve hot.
