Step 1

Arrange a rack in the middle of the oven and heat to 450°F. Let the pizza dough sit out a room temperature while the oven heats.

Step 2

Mix together the ricotta, mozzarella, dried basil, salt, and red pepper flakes in a small bowl; set aside.

Step 3

Lightly grease a rolling pin with olive oil. Roll out the pizza dough to fit a standard 13x18-inch rimmed baking sheet. Transfer the dough to the baking sheet, then use your fingers to gently press the dough into the corners of the pan.

Step 4

Spread the cheese mixture over the dough, leaving about a 1-inch border around the edges. Arrange the vegetables in a rainbow pattern on top of the cheese. Drizzle with olive oil, or coat the veggies with a thin layer of cooking spray.

Step 5

Bake until the edges are golden-brown, 16 to 20 minutes. Let the pizza cool for 1 to 2 minutes before cutting into slices and serving.
