How to Make It
Whisk together eggs, salt, and black pepper in a medium bowl until frothy. Set aside.
Cook sausage in a large skillet over medium-high, stirring to break up pieces, until browned, about 10 minutes. Transfer sausage to a plate lined with paper towels. Reserve 2 teaspoons drippings in skillet.
Reduce heat to medium. Add bell pepper and onion to skillet; cook, stirring often, until softened, about 5 minutes. Add harissa; stir to combine. Add eggs and cooked sausage; cook, stirring gently, until eggs are just set but still creamy, 1 to 2 minutes.
