Step 1

Preparation Heat oil in a large heavy skillet (preferably cast iron) over medium-high. Cook chorizo, breaking up into small pieces with a wooden spoon, until browned and cooked through, about 5 minutes. Transfer to a bowl with a slotted spoon; reserve skillet with fat.

Step 2

Add butternut squash and onion to reserved skillet and cook over medium-high, adding more oil if needed and stirring occasionally, until golden brown and tender, 10–15 minutes. Stir in chorizo and season with salt. Squeeze a lime wedge over and top with cilantro. Serve with additional lime wedges for squeezing over.
