Preheat your oven to 425 degrees f. and line a 12-inch round pizza baking tray with parchment paper.

Place your cauliflower florets into a food processor and pulse until it resembles a fine meal. Transfer to a large bowl.

Add in the mozzarella, Parmesan, eggs, oregano, sea salt, and pepper. Stir thoroughly to combine.

Place the cauliflower mixture onto your prepared baking tray and form it into a ½-inch-thick circle. Make sure the edges are not thinner than the center or they may brown too fast.

Bake your crust at 425 degrees f. for 20-25 minutes, or until the edges are golden.

Meanwhile, heat a grill pan or an outside grill over medium-high heat.

Drizzle the eggplant and onion slices with oil and season with sea salt and pepper. Gently rub to coat both sides.

Grill your veggies for 2-4 minutes per side, or until grill marks appear.

Once your cauliflower crust is done, remove from the oven and layer the marinara sauce over the crust.

Top your pizza with the grilled veggies and olives as desired.

Sprinkle with the mozzarella and Parmesan cheese, and bake for 8-10 minutes, or until the cheese is nicely melted and golden brown.

Garnish with fresh basil leaves and enjoy!
