Instructions

Step 1: Preheat a grill or grill pan to medium-high heat. While heating, toss 1 large thinly sliced yellow onion with 2 tbsp olive oil, 1/2 tsp salt, and 1/4 tsp black pepper in a bowl.
Step 2: Spread the onions on a grill-safe pan or foil and grill for 15 minutes, stirring every 5 minutes until deeply browned and caramelized. Remove from grill and set aside.
Step 3: Place 4 Italian sausage links on the grill and cook for 12-15 minutes, turning every 3-4 minutes until cooked through and nicely charred on all sides.
Step 4: While sausages cook, slice 4 hoagie rolls lengthwise but not all the way through and toast them cut side down on the grill for 1-2 minutes until golden.
Step 5: Spread 1 tbsp Dijon mustard inside each toasted hoagie roll. Add a grilled sausage link, top with a generous scoop of caramelized onions, and garnish with 1 tbsp pickled banana peppers. Serve hot.
