1Heat gas or charcoal grill for indirect cooking and medium heat. Generously spray 18x18-inch piece of heavy duty foil with cooking spray.*
2To measure Bisquick mix, lightly spoon into measuring cup; level off. In medium bowl, stir together all crust ingredients just until dry ingredients are moistened. Lightly knead dough in bowl 10 times. Place dough on sprayed foil; starting at center, press into a 12-inch round. Place on large cookie sheet to carry to grill. Place crust on grill, foil side down. Cook covered 1 to 3 minutes or until bottom of crust is light golden brown. Do not over cook. Remove from grill to cookie sheet.
3Spread sauce over dough to within 1/2-inch of edge. Top evenly with remaining ingredients (do not make thicker in center or center won't get done). Carefully place pizza on grill, foil side down. Cook covered, 8 to 10 minutes or until bottom of crust is deep golden brown and cheese is melted. Carefully place on cookie sheet. Sprinkle with basil.
