Wash and trim the outer leaves from Brussels sprouts. Cut large ones in halves or quarters.
Combine Brussels sprouts and garlic in a large bowl. Drizzle balsamic vinegar, olive oil, and honey over the sprouts. Sprinkle with salt and pepper. Toss to coat.
Pour onto a rimmed baking dish. Spread evenly into one layer, don't overcrowd the pan. Roast for 25-30 minutes or until brown, tender and crispy.
Taste and add more seasoning if needed. Transfer to a serving dish and sprinkle with feta cheese before serving.
