2. Place bread in a food processor; process 30 seconds or until finely ground (can also use prepared breadcrumbs). Place breadcrumbs in a large bowl. Add milk to breadcrumbs; toss with a fork to moisten. Add salt, pepper, and beef to breadcrumb mixture, stirring just until combined. Divide meat mixture into 16 equal portions, shaping each into a 3 1/2-inch patty. Spoon 1 tablespoon cheese in the center of each of 8 patties; top each with 1 remaining patty, pinching edges to seal.
3. Place patties on grill rack coated with cooking spray; grill 4 minutes on each side or until desired degree of doneness. Remove from heat; keep warm.
4. Lightly coat cut sides of rolls with cooking spray; place cut sides down on grill rack, and grill 30 seconds or until toasted. Serve patties on toasted rolls with desired toppings.
