Wash brussels sprouts and trim off the tough stem end. Remove any leaves that are sticking out and cut each sprout in half. Place sprouts in a large bowl.
In a small bowl combine olive oil, vinegar, salt, and garlic.
Pour vinegar mixture over brussel sprouts and stir until they are well dressed.
Spread sprouts out on a large lined baking sheet in an even layer.
Bake at 425° for 20-25 minutes or until sprouts are tender and starting to char just slightly around the edges.
