This crisp, cheesy pizza is thin on calories but packed with flavor. Whole-wheat tortillas have fewer carbs than thick pizza crusts and get crisp in the oven. Pair with a green salad to round out the meal with vitamins and minerals.
Preheat oven to 450 degrees with racks in upper and lower thirds. Place tortillas on two rimmed baking sheets; brush with 1 teaspoon oil. Dividing evenly, top with tomatoes, cheeses, olives, and red-pepper flakes. Bake until crust is crisp and browned, 13 to 15 minutes, rotating sheets halfway through.
Meanwhile, make vinaigrette: In a medium bowl, whisk together remaining 2 teaspoons oil and vinegar; season with salt and pepper.
When pizzas are finished baking, toss arugula with vinaigrette. Top pizzas with basil, and cut into wedges; serve with arugula salad.
