Preheat oven to 350 degrees.
Place halved bagels on a greased baking sheet.
Melt butter and season the butter with garlic powder and Italian seasoning to taste.
Brush seasoned melted butter onto bagels.
Pre-bake the bagels in the oven for 5 minutes at 350 degrees.
Remove the bagels from the oven and brush pizza sauce on the bagels.
Sprinkle on mozzarella cheese.
Top with pepperoni and banana peppers. (I like to sprinkle on a little bit more mozzarella cheese on top of that)
Bake the pizza bagels an additional 5 minutes in the oven at 350. Then, broil on high for a few minutes keeping a close eye on them. You want the cheese nice and melted but be careful not to burn them.
Serve and enjoy!
