Place the broccoli into a large pot with about 1-inch of water in the bottom. Bring to a boil, & cook for 7 minutes, or until tender but still crisp. Drain. Place in a serving bowl.

While the broccoli is cooking, melt the butter in a small skillet over medium heat. Mix in the brown sugar, soy sauce, vinegar, pepper, & garlic. Bring to a boil, then remove from the heat. Mix in the peanuts.

Pour the sauce over the broccoli. Serve immediately.
