Warm a skillet over medium heat. Warm the oil, then add the chorizo with casings removed. Brown the sausage in the skillet, stirring frequently to prevent sticking.
Remove from the pan and place on a paper towel-lined plate to drain the grease. In an oven-safe dish, stir together the cooked chorizo and green chiles. Sprinkle cheese evenly over the top.
Bake in preheated oven for 10-12 minutes or until the cheese is bubbly.
While hot, spoon pico de gallo over top and garnish with fresh cilantro.
Serve hot with flour tortillas or tortilla chips.
Notes
You do not need a lot of oil for cooking the chorizo as it has a high fat content.
Be sure to drain the grease so you don’t have an oily queso.
To prevent a chewy texture, don’t overcook the mixture. Start checking it a few minutes before it should be done and remove when the cheese begins to bubble.
