Sausage And Broccoli Rabe Frittata

• 12 large eggs
• 1/2 cup whole milk
• 3/4 cup grated cheddar, divided
• Kosher salt, coarsely ground pepper
• 2 tablespoons vegetable oil
• 1/2 medium onion, chopped
• 1/2 pound fresh Spanish chorizo or hot Italian sausage links, casings removed
• 1 bunch broccoli rabe, coarsely chopped

1. Preheat broiler. Whisk eggs and milk in a medium bowl. Mix in 1/2 cup cheddar; season with salt and pepper and set aside.
2. Heat oil in a large skillet, preferably castiron, over medium heat. Add onion and chorizo and cook, stirring occasionally, until onion is softened and chorizo is brown, 6-8 minutes. Add broccoli rabe; season with salt and pepper and cook, stirring occasionally, until tender, 8-10 minutes longer.
3. Reduce heat to low and pour reserved egg mixture over vegetables. Cook, shaking pan occasionally, until edges are just set, 10-12 minutes. Top frittata with remaining 1/4 cup cheddar; broil until top is golden brown and center is set, about 4 minutes longer.
4. Cut frittata into wedges and serve warm or room temperature.
