Preheat oven to 400°F.
Slash an “X” through chestnuts; on the flat side of nut. Place them, cut side up on a cookie sheet and roast for 20 minutes. When cool enough to handle, remove husk. Cut chestnuts into small pieces and set aside.
* You can substitute raw walnuts for chestnuts. Roast walnuts for 5 minutes.
Clean and trim sprouts. If sprouts are large, cut in half vertically. Heat oil in a large skillet and sauté red pepper for 3 minutes. Add Brussels sprouts and sauté 3 more minutes.
Add water, cover, and steam about 5 minutes. Remove lid, stir in chestnuts, and cook, uncovered, until chestnuts are warmed through and sprouts are tender, being careful not to overcook sprouts. Serve immediately.
