- Place the rack in the lowest position of the oven. Top with a pizza stone or an upside-down baking sheet. Preheat the oven to 250 °C (500 °F).
- In a bowl, combine all the ingredients. Season with salt and pepper. Set aside.
- Place the pizza crusts, frozen or slightly thawed on two separate sheets of parchment paper. Spread with the tomato sauce. Garnish with the capicollo, bell pepper, and cheese.
- Place the pizza with the parchment paper on the hot baking sheet. Bake for about 8 minutes or until the crust is golden brown. Bake one at a time if the baking sheet or stone seems too small. Cut into wedges and serve.
For a slightly softer crust, allow the frozen crust to come to room temperature while preparing the ingredients, about 15 minutes.
