Step 1

Preheat oven to 300°F. Remove the chorizo from its casing (if any) and grate the cheese on the largest holes of a box grater.

Step 2

Set an oven-safe skillet over medium heat, and add the tablespoon of oil. Cook the chorizo for 7 to 8 minutes, until the fat renders and the sausage is bubbly.

Step 3

Drain the fat from the skillet, reserving 3 tablespoons of chorizo for garnish. If it's very greasy, place it on top of paper towels to get as much fat off of it as possible before putting it back in the pan. Top the chorizo with the grated cheese.

Step 4

Place the skillet in the oven and cook for 5 to 7 minutes, until the cheese is melted and bubbly. Place the skillet on a heat-proof surface, garnish with reserved chorizo, and serve immediately.
