Step 1
Slice kielbasa on the bias into 1/2-inch-thick rounds. Slice onion into thin rings.
Step 2
Heat oil in a large skillet over medium-high. Add onions, stir often until golden and charred, 6–7 minutes.
Step 3
Push onions to the side. Lay kielbasa slices flat on the hot skillet in a single layer.
Step 4
Sear kielbasa without moving for 2 minutes, then flip and sear 1–2 minutes more until edges are browned.
Step 5
Drizzle mustard over the kielbasa and onions. Toss to coat, cooking 30 seconds until glossy.
Step 6
Season with salt and pepper. Serve hot from the skillet.
