Boudin Blanc with Broccoli Rabe and Grainy Mustard

Heat oven to 400 degrees. Slice sausages in half lengthwise. Place, cut side down, in skillet over medium heat; sear until golden, 5 minutes. Cook 2 to 3 minutes more, until cooked through. Transfer to baking sheet; warm in oven.

To skillet, add oil, garlic, and red pepper. Saute until garlic is fragrant, about 30 seconds. Add broccoli rabe; saute until al dente, about 5 minutes. Season with salt and pepper.

Slice open rolls; toast, about 5 minutes. Spread with mustard. Place one sausage on each roll; mound broccoli rabe over sausage.
