Step 1

Preheat oven to 400 degrees F. Line a bake sheet with foil.

Step 2

Trim off bottoms of Brussels sprouts and cut in half (or cut in quarters if they are larger than 1 inch). Place into a large bowl.

Step 3

Chop the onion and bacon into 1/2 inch pieces and add to the bowl with the sprouts. Add the oil and toss to coat well.

Step 4

Spread the mixture evenly on the bake sheet and roast 20-25 minutes until tender and browned, tossing once during the roasting.

Step 5

Remove pan from the oven and drizzle Brussels sprouts with the vinegar and salt and pepper, tossing well. Serve hot or at room temperature.
