Charred grilled Italian sausage with peppers and onions on a crusty roll is a high protein, family-favorite cookout classic. This savory, carnivore-approved dish is easy and always satisfying.
Preheat grill to medium-high heat, about 400°F, and oil the grates lightly for easy turning.
Slice the red and yellow bell peppers and onion into thick strips; toss with olive oil, salt, and black pepper.
Place sausage links on the grill and cook for 6–8 minutes per side, turning occasionally for even charring.
Grill peppers and onions in a grill basket or directly over the grates, stirring frequently until tender and lightly caramelized, about 10 minutes.
To assemble, place each sausage on a crusty roll, top generously with grilled peppers and onions, and serve immediately while hot.
