If you're a fan of both ratatouille and pizza, why not combine the two? Ratatouille pizza is made by spreading a layer of tomato sauce on a pizza crust and then topping it with sautéed ratatouille vegetables and cheese. The pizza is then baked until the crust is crispy and the cheese is melted and bubbly. It's a delicious and creative way to enjoy the flavors of ratatouille.
