I've been making this sweet and spicy sandwich filling for 35 years. It smells as good as it tastes! It's a great reward for a hungry family after a day working or playing outdoors. —Elaine Krupsky, Las Vegas, Nevada

In a Dutch oven, cook beef and sausage over medium heat until no longer pink, breaking both into crumbles; drain. Place a third of the onions and peppers in a 5-qt. slow cooker; top with half the meat mixture. Repeat layers; top with remaining vegetables. Sprinkle with salt, pepper and pepper flakes.
Cover and cook on low for 3-4 hours or until vegetables are tender. With a slotted spoon, serve about 1 cup of meat and vegetables on each roll. Top with cheese if desired. Use pan juices for dipping if desired.
