Brussels sprouts, Olive Oil, Black Pepper, Sea Salt, Balsamic Vinegar: Preheat oven to 375°. Trim the stem end off the rinsed Brussels sprouts, remove any bad leaves, then cut the sprout in half lengthwise. Place in a bowl & add enough olive oil to lightly coat them. Sprinkle with salt & pepper. Now add a tablespoon of balsamic vinegar. Toss ingredients & place on a non-greased baking sheet cut side down. Place in oven & roast 15 minutes. Then turn the sprouts over & cook another 15 minutes.
