Ingredients
  

Kielbasa & Veg
  • 1.5 lb smoked kielbasa
  • 2 red bell peppers
  • 1 green bell pepper
  • 1 yellow bell pepper
  • 2 yellow onions
  • 3 tbsp olive oil
Seasoning
  • 1 tsp smoked paprika
  • 0.5 tsp garlic powder
  • 0.5 tsp onion powder
  • 0.5 tsp black pepper
  • 0.25 tsp crushed red pepper flakes optional
  • 0.5 tsp kosher salt
Optional for Serving
  • 1 hoagie rolls or crusty bread
  • 1 whole-grain mustard
  • 0.25 cup fresh chopped parsley

Equipment

  • 1 cast iron skillet
  • 1 grill basket
  • 1 foil-lined grill pan

Method
 

Preheat and prep
  1. Preheat your grill to medium-high heat, about 400°F. If using a cast iron grill pan indoors, heat it over medium-high until very hot.
  2. In a large bowl, toss the sliced peppers and onions with olive oil, smoked paprika, garlic powder, onion powder, black pepper, red pepper flakes, and salt. Toss until every strip is well coated.
Caramelize the peppers and onions
  1. Spread the seasoned peppers and onions onto a grill basket or a foil-lined grill pan. Grill for 12–15 minutes, tossing halfway, until softened, slightly charred at the edges, and caramelized.
Grill the kielbasa
  1. Place the kielbasa rounds directly on the grill grates. Grill for 3–4 minutes per side until you get deep golden-brown grill marks and the cut sides develop a caramelized crust.
Combine and serve
  1. Once the kielbasa is charred and the peppers are tender, toss everything together directly on the grill for 1–2 minutes to let the flavors meld.
  2. Remove from the grill and let rest for 2 minutes. Pile onto hoagie rolls or serve over rice, then finish with whole-grain mustard and fresh chopped parsley if desired.
  3. Serve immediately while everything is sizzling hot.

Notes

For best caramelization, avoid moving the peppers and onions too early—let them sit long enough to brown before tossing. Refrigerate leftovers in a sealed container for up to 3 days; reheat in a skillet over medium heat until hot. Freezing isn’t recommended because peppers soften too much. If you want a lighter option, choose turkey kielbasa to reduce saturated fat while keeping the smoky char method.
