Preheat the oven to 425°F (220°C). Spread the bread with a thin layer of butter and place on a baking tray. When the oven is hot, place the bread in the oven and bake for about 5-6 minutes or until golden (keep an eye on it to not burn it).
Take the toasted bread out of the oven. Tu rn it over and spread 2 tablespoons of pizza sauce on each slice of toast.
Top with sliced ham.
Place smoked gouda slices on top, then sprinkle shredded mozzarella. Place all your favorite toppings on top - in my case - sauteed sliced mushrooms, finely diced bell pepper, and canned corn.
Bake for 6-7 minutes or until the cheese is melted.
Drizzle a small amount of pesto on each toast.
Enjoy!
Notes
For a simpler pizza toast, you can just use pizza sauce, mozzarella, and pepperoni.
You could also toast the bread under the broiler/grill but you need to keep an eye on it in order not to burn it. Air fryer and toaster oven also work great, especially for a small batch.
Calories = 1 pizza toast (1/4 of the recipe). This is only an estimate!
