Grill polish sausage until the casing starts to break. (Should have a little bit of a char) Let cool and slice sausage diagonally into 1/2 inch pieces.
While the sausage is cooking roll out a piece of aluminum foil to a size of 12 x 14 inches. Spray the aluminum foil on one side with cooking spray.
Place the crust in the center of the foil and push it out to the edges of the foil to form a rectangular crust; spray the top of the dough with cooking spray.
Lower the grill heat to medium low and place the crust on the grill dough side down and gently peel off the aluminum foil. (save the foil)
Grill uncovered until crust is golden brown. (Watch the crust closely this only takes a few minutes.) Using a large spatula flip the crust and cook just until the crust firms up – slide the crust back onto the piece of aluminum foil browned side up.
Spread the tomato sauce over the crust, sprinkle on the basil, and 1 3/4 cups of cheese. Then distribute the sausage and pepper evenly over the top.
Top with the remaining cheese; slide the pizza off the aluminum foil back onto the grill, and grill covered until crust is brown and cheese is melted.
