Crust:
1-1/2 cups all-purpose flour
1/2 cup whole wheat flour
1 package (1/4 ounce) quick-rise yeast
1/2 teaspoon salt
1/2 teaspoon sugar
3/4 cup warm water (120-130 F)
1 tablespoon olive or canola oil
Pesto:
1 cup chopped fresh basil
1/4 cup fat-free plain yogurt
2 tablespoons unsalted sunflower kernels
1 tablespoon olive or canola oil
1 garlic clove, minced
1/8 teaspoon salt
1/8 teaspoon pepper
Toppings:
1 cup (4 ounces) shredded part-skim Mozzarella cheese, divided
2 medium tomatoes, thinly sliced
2 green onions, finely chopped
Coarsely ground pepper
2 tablespoons grated Parmesan cheese

Coat grill rack with nonstick cooking spray before starting grill. Prepare grill for indirect medium heat.

In a mixing bowl, combine flours, yeast, salt and sugar. Add water and oil; mix just until a soft dough forms. Turn onto a floured surface; knead until smooth and elastic, about 5 to 7 minutes. Cover and let stand for 10 to 15 minutes.

Meanwhile, combine the pesto ingredients in a blender or food processor. Cover and process until smooth, scraping sides often. Set aside.

Divide dough into fourths. Roll each portion into a 6-inch circle; place on grill over directly heated area. Cover and cook for 1 minute or until puffed and golden. Turn; place over indirectly heated area of grill. Spread pesto over crusts; top with 2/3 cup Mozzarella cheese, tomatoes, onions, pepper, Parmesan and remaining Mozzarella. Grill for 3-5 minutes or until cheese is melted and crust is lightly browned.
