Grilled Sausage Pizza-Healthy

My family loves these grilled pizzas. If you follow the recipe, it makes for a healthy meal. I got this from a family member.

Grilled Pizza with Sausage, Tomatoes, and Basil

1 ¼ c. all-purpose flour
1 ½ tsp. yeast
1 tsp. salt
Vegetable oil cooking spray
1 lb. red and yellow cherry tomatoes, halved
½ lb. turkey sausage, cooked and thinly sliced

(I some times use ground sausage instead)
1 c. grated part-skim mozzarella
1 Tbsp. chopped fresh basil
1 Tbsp. balsamic vinegar
1 Tbsp. olive oil
½ tsp. salt
½ tsp. red pepper flakes
Sliced red, yellow, and orange peppers

Mix flour, yeast and salt in a bowl. Gradually add ½ c. warm (110° F) water until a soft dough forms. Divide dough into 4 portions. Using hands, roll dough into balls, coat with cooking spray, cover with plastic wrap and set aside to rise 30 to 45 minutes. When ready to cook, place each ball of dough on a piece of wax paper and flatten into a 4-inch circle. Coat grill with cooking spray and heat on high. Gently lift dough onto grill and cook until dough puffs and underside stiffens (about 30 seconds); flip and reduce heat to low. Mix topping ingredients, then divide among crusts; cover grill. Grill until cheese melts, 5 to 6 minutes more. Slice and serve.
