Step 1

Preheat the oven to 400ºF. Wash and slice the potatoes into 1-inch pieces. Slice the kielbasa into medallions. Dice the onion into 1-inch pieces.

Step 2

Add the potatoes, kielbasa, onion, and frozen green beans (no need to thaw) to a large baking sheet. Drizzle with olive oil and sprinkle the steak seasoning over top. Use your hands to toss the ingredients until everything is coated in oil and spices.

Step 3

Transfer the baking sheet to the oven and roast in the oven for 20 minutes, then give the ingredients on the sheet pan a good stir. Roast for an additional 15 minutes, or until the ingredients achieve the level of browning you desire. Serve hot.
