Grill sausage, onion and pepper slices. When sausage is cool to handle, cut into 1/4-inch-thick slices.
On floured surface with floured rolling pin, roll pizza dough into two 10-inch round circles, 1/4-inch-thick. Combine olive oil, TABASCO® Sauce and garlic in small bowl. Carefully place dough rounds on grill. Cover grill; dough will puff slightly in 2-3 minutes. With tongs and spatula, immediately flip dough onto coolest part of grill. Quickly brush the grilled surface of dough with oil mixture. Top dough with sausage, peppers, onion and cheese. Slide pizzas back on hot part of grill. Rotate pizzas frequently so as not to burn. Pizzas are done when top is bubbling and cheese is slightly melted. Serve immediately.
Makes 2 pizzas or 4 servings.
