Yield
Serves: 4
Preparation
Bring a few inches of water in a deep skillet to boil. Season with salt and add rapini/broccoli rabe, cook 3 minutes and drain. Return pan to heat and add olive oil, 3 turns of the pan. Add red pepper and garlic, and stir a minute. Add broccoli rabe and toss 2-3 minutes more; adjust salt to taste.
Heat a cast-iron skillet or griddle pan over medium-high to high heat.
Combine sausage and beef with Worcestershire, grated onion, salt and pepper. Form 4 patties, making them thinner at the center and thicker at the edges for even cooking. Drizzle the burgers with olive oil and cook the patties 10 minutes, turning occasionally. Top with cheese in the last minute or two and melt under a foil tent.
Place giardiniera relish on focaccia or roll bottoms. Top with a burger patty, some broccoli rabe and potato chips; set focaccia/roll tops in place.
