Unroll dough on a large baking sheet which has been sprayed with non-stick cooking spray.
Spoon the pesto on the pizza dough and spread out evenly.
Heat a heavy-duty skillet over medium-high heat. Add olive oil and tomatoes. Sauté for about 5 minutes or until the tomatoes are charred and beginning to break down. Add in the garlic, Italian seasoning, and crushed red pepper flakes and saute about 1 minute. Mix well and remove from the heat.
Spoon the tomato mixture over the pizza evenly. Add the artichoke hearts, mozzarella cheese slices and grated Havarti.
Place the pizza in the oven and bake 15-20 minutes or until the crust is crisp and brown. (The more toppings that are on the pizza, the longer it will take to cook.)Loosen the pizza with a metal spatula and cut into slices! Enjoy!
