Preheat the oven to 425℉ and add a large sheet pan to the oven so it heats up.
Add the cut Brussels sprouts to a large bowl and set aside.
In a medium bowl, whisk together the strawberry preserves, balsamic vinegar, extra virgin oil, lemon juice, garlic powder, paprika, and salt & pepper to taste. Reserve about 2 tablespoons of the sauce for serving. Pour the rest of the sauce over the Brussels sprouts and toss until they are completely covered.
Carefully take the hot sheet pan out of the oven. Add the seasoned brussels sprouts, cut side down, to the hot pan.
Roast for about 20 minutes, or until there is a browned crust on the cut side.
Allow the roasted Brussels sprouts to cool on the pan for 1 minute before removing them with a spatula.
Pour remaining sauce over the Brussels sprouts and top with crumbled feta, if desired. Enjoy!
