Cheesy Sausage & Broccoli Rabe Melt

Directions

1. Preheat oven to 400°F.
2. Add a ½ inch water to a large skillet, then add the sausages. Bring the water to a boil, then reduce to a simmer, cover, and cook for 10 minutes, or until a meat thermometer registers about 165°F. Transfer the sausages to a plate.
3. Bring a large pot of water to a boil. Fill a large bowl with ice water and place it close to the pot. Add the broccoli rabe to the boiling water and cook for about 1 minute, then transfer immediately to the ice water to stop the cooking. Drain the broccoli rabe and chop into bite-sized pieces.
4. Heat the olive oil in a large skillet over medium-high heat. Add garlic and cook, stirring constantly, for 30 seconds to 1 minute until garlic is just beginning to brown and smells fragrant.
5. Add the chopped broccoli rabe, salt, red pepper, and Gruyère, and cook just until the cheese melts.
6. Split the rolls open without fully separating the tops and bottoms and place them on a baking sheet. Place one sausage on each roll then divide the broccoli mixture between each. Top with the sliced mozzarella and put the baking sheet in the oven and bake for about 5 minutes, or until the cheese is melty. Serve hot.
