Preheat your oven to 425 degrees. Line a baking tray with foil for easy cleanup.
Slice your pepperoni into heart shapes using a knife or cookie cutter. Place 3 onto each piece of toast.
Place on your baking tray and cook 5-7 minutes or until the cheese is melted and the edges of the toast are slightly crisp. Serve immediately.
Notes
You can always use regular garlic toast. Just add a sprinkle of cheese. Make this even more like pizza by topping with sauce before adding your toppings!
