Remove CAULIPOWER Cheese Lovers pizza from freezer. Add the two circular slices of green bell pepper to the pizza creating the "clouds", one on each side of the pizza.
Create the rainbow by first placing the pepperoni on the pizza in an arch shape, connecting at the circular pepper clouds.
Add the orange bell pepper under the pepperoni, then add the yellow bell pepper, green bell pepper, and red onion.
Fill in the clouds with black olives. Bake pizza according to package instructions, slice, and enjoy!
