Cut the bottom of the brussels sprouts and then slice in half.
Add the halved brussels sprouts to a large bowl, dress with avocado oil, salt and pepper. Toss to ensure they are evenly covered.
Spread brussels sprouts evenly on a baking sheet. Place in preheated oven and bake for 20-25 minutes or until sprouts are tender and golden brown. I usually cook mine until the single leaves that have fallen off of the sprouts are crispy.
While the brussels sprouts cook, combine the balsamic vinegar and maple syrup in a small bowl.
Pour the maple balsamic sauce over the cooked brussels sprouts and toss. Serve immediately or you can place back in the oven for about 5 minutes to thicken and reduce the sauce slightly, but keep an eye on them to prevent the sugars from burning.
