Cauliflower Pizza Casserole 

Ingredients

1 large cauliflower, cut into florets
1 tbsp olive oil
2 cups pizza sauce
2 oz pepperoni (I use Yives Vegetarian pepperoni)
1/4 cup black olives, sliced
1 cup mozzarella, shredded
1/4 cup parmigiano reggiano (parmesan), grated
1/4 tsp oregano (optional)

Instructions

Preheat oven to 400F
Toss the cauliflower in the oil, place on a baking sheet in a single layer and roast until it starts to caramelize (about 20-30 minutes) mixing half way through.
Turn oven down to 350F
Mix the cauliflower, pizza sauce, pepperoni and olives, reserving some pepperoni and olives, place in a baking dish, sprinkle on the cheese followed by the reserved toppings and the oregano.
Bake until the cheese has melted and the sides are bubbling (about 20 minutes).
