Instructions

  1. Step 1: Preheat grill to medium-high heat (about 400°F). Brush 4 pork bratwurst links with 1 tbsp olive oil and season lightly with 1/4 tsp black pepper.
  2. Step 2: Place bratwurst on the grill and cook for 12-15 minutes, turning every 3-4 minutes until browned and internal temperature reaches 160°F.
  3. Step 3: While the bratwurst cooks, prepare the spicy mustard aioli by whisking together 1/4 cup yellow mustard, 1/4 cup mayonnaise, 1 tbsp Dijon mustard, 1 tbsp Sriracha sauce, and 1 minced garlic clove in a small bowl until smooth.
  4. Step 4: Lightly toast 4 hoagie rolls on the grill for 1-2 minutes until warm and slightly crisp.
  5. Step 5: To assemble, spread 2 tbsp of the spicy mustard aioli inside each roll, add one grilled bratwurst link, and top with 1/4 cup drained sauerkraut.
  6. Step 6: Serve immediately, allowing the tangy sauerkraut and spicy aioli to complement the savory bratwurst.
