Heat a skillet over medium heat and add the homemade ground chorizo. Cook until browned, about 5-7 minutes.

Add the diced white onion to the skillet and cook until softened and translucent, around 3-4 minutes.

In a bowl, crack the 10 large eggs, season with salt and pepper, and whisk until combined.

Pour the egg mixture into the skillet over the chorizo and onion. Stir gently until the eggs are cooked through and fluffy, about 5-6 minutes.
