Combine brussels sprouts, grapes, and garlic in a large bowl. Drizzle with extra virgin olive and season with salt and pepper. Toss everything together until the brussels sprouts and grapes have a nice light coating of the olive oil and seasoning.
Spread everything out a rimmed baking sheet and roast for 25-30 minutes, flipping half way through, until brussels sprouts are golden brown.
Transfer to your favorite serving dish and drizzle with 1 tablespoon balsamic glaze. Enjoy!
