Preheat oven to 425°F.
In a medium bowl, mix pizza dough according to package directions. Cover and set aside for 5 minutes.
In a small frying pan, prepare sausages according to package directions. Cut into small pieces and set aside.
Spray a flat cookie sheet or pizza pan with non-stick cooking spray (you can also use an oven/grill-safe pizza pan). On a floured cutting board or prep surface, press or roll out dough with hands/rolling pin (using additional flour on hands/rolling pin to prevent sticking), until crust is at your desired thickness.
Place dough on the cookie sheet/pizza pan and bake in the oven about 3 minutes, or until the crust is no longer doughy (do not over-bake).
Remove crust from the oven and brush lightly with olive oil. Spread crust with pizza sauce. Top with onion, pepperoni and sausages. Sprinkle evenly with Cooper Cheese. Distribute the olive slices and pepper rings. Sprinkle with feta cheese.
On a pre-heated grill, either a) if using a cookie sheet, slide the pizza directly to the rack, or b) if using a grilling pan, place pan directly on the grill. Cook, covered, until pizza crust is browned and cheese is melted.
Remove from the grill, slice and serve!
