Step 1
Slice kielbasa on a diagonal into 1/2-inch-thick pieces. Preheat a grill or large skillet to medium-high.
Step 2
Grill or sear kielbasa 2 minutes per side until edges are charred and golden. Transfer to a plate.
Step 3
Thinly slice the onion. Add oil to the same pan and sauté onion over medium heat, stirring occasionally.
Step 4
Cook until onion turns deep golden brown and crispy at the edges, 8–10 minutes. Add caraway seeds if using.
Step 5
Return kielbasa to pan and toss to combine. Stir in mustard and toss until evenly coated.
Step 6
Season with salt and pepper. Serve hot straight from the pan or on a platter.
