Preheat oven to a toasty 450F. Either brush the pieces of bread lightly with oil or spray both sides with cooking spray. Place in oven for 1 to 2 minutes to harden and toast the crust.
Remove from oven and add the sauce.
Add cheeses, mozzarella first. Then add toppings of your choice (don’t go too overboard…), being sure to log all topping macros.
Cook for an additional ~3-6 minutes to melt cheese.
