Step 1
Slice kielbasa into 0.5-inch thick rounds. Cut onions in half, then slice into 0.25-inch-wide wedges.
Step 2
Heat oil in a 12-inch skillet over medium-high until it shimmers, about 90 seconds.
Step 3
Add kielbasa rounds in a single layer. Sear 3 minutes until edges crisp and edges darken, then flip and cook another 2 minutes.
Step 4
Transfer kielbasa to a plate. Keep heat at medium, add onions and salt to the skillet.
Step 5
Cook onions, stirring occasionally, until soft and golden brown, about 8 minutes. You'll smell sweet caramel notes.
Step 6
Return kielbasa to the skillet, toss with onions, and cook 1 minute until heated through. Taste and adjust seasoning.
Step 7
Divide kielbasa and onions among plates. Serve with a dollop of whole-grain mustard on the side.
