1
Preheat the grill to medium heat or the oven to 375 degrees F.
2
Place the kielbasa, potatoes, bell pepper and onion in a large bowl. Drizzle with olive oil, season with salt and pepper, and toss to evenly coat. Place an equal portion on each of the 4 pieces of foil.
3
Bring the short sides of the foil together, and fold them at the top. Then fold over the open sides, crimping to seal. Avoid folding the packets too tightly; you want a little air space at the top of each packet. You do, however, want the edges to be sealed tightly.
4
Grill, covered, for 20 to 30 minutes, flipping the packets once halfway through, or until the potatoes are tender.
5
Carefully open the packets so the steam doesn’t burn you. When baking in the oven, you may wish to broil the opened packets for 1 to 2 minutes, watching closely, to lightly brown on top.
