Step 1

Heat oven to 500°F (if you can’t heat the oven this high without broiling, heat to 475°F).

Step 2

On a lightly floured surface, shape the pizza dough into a 14-in. oval. Place on a cornmeal-dusted or parchment-lined baking sheet. Sprinkle Cheddar over top.

Step 3

In a large bowl, toss onion and peppers with olive oil and 1/4 tsp each salt and pepper. Scatter over dough and bake until the crust is golden brown, 10 to 12 minutes.
