Preheat oven to 400°. Microwave bacon slices, in batches, between paper towels, at HIGH for 1 1/2 minutes. Cut slices in half crosswise. Cut Brussels sprouts in half lengthwise. Wrap 1 bacon piece around each Brussels sprout half; secure with a wooden pick. Place sprouts, cut sides down, on a lightly greased wire rack on a baking sheet. Sprinkle with pepper to taste. Bake at 400° for 20 to 25 minutes or until bacon is crisp and Brussels sprouts are tender. Serve with Creamy Mustard Sauce, if desired.
Creamy Mustard Sauce: Stir together 1/2 cup sour cream, 2 tsp. whole grain mustard, 1 tsp. brown sugar, and salt and pepper to taste in a bowl. Makes 1/2 cup. Prep: 5 min.
