½ bunch Asparagus, sliced
½ cup caramelized Onions
1 cup Spinach or Swiss Chard, chopped
¼ lb Sausage, cut into pieces
2 tbsp Olive Oil
Place oven-proof skillet over medium heat. Add a Tbsp of oil and the sausage pieces. Cook until mostly done, about 2-3 minutes each side.
Meanwhile, crack the eggs into a large bowl, add a pinch of salt, and beat until well combined. Stir the caramelized onions into the eggs, and set aside.
Stir in the asparagus, scraping up any bits stuck to the pan. Cook for another 2-3 minutes.
Add the spinach and cook for another minute. Pour egg mixture into the pan and distribute ingredients into an even layer. Continue to cook on medium low for about 5-8 minutes.
When eggs have mostly set, but there’s a little liquid left on top, start the broiler. Place skillet under broiler and cook, checking every 1-2 minutes, until the frittata is fully set.
