Sausage and Pepper Sheet-Pan Sandwiches

Directions

1. Preheat oven to 375°. Place sausage pieces in a 15x10x1-in. sheet pan, arranging peppers and onion around sausage. Drizzle olive oil over sausage and vegetables; bake, stirring mixture after 15 minutes, until sausage is no longer pink and vegetables are tender, 30-35 minutes.
2. During the last 5 minutes of baking, arrange buns cut side up in a second sheet pan; top each bun bottom with a cheese slice. Bake until buns are golden brown and cheese is melted. Spoon sausage and pepper mixture onto bun bottoms. Replace tops.
