Queso Fundido is a hot cheese dip that has melted White Cheddar, Monterey and Pepper Jack cheeses and a layer of spicy chorizo sausage, onions and poblano peppers on top.
In a cast iron skillet or frying pan over medium high heat add the oil. Heat for a minute and add the sliced poblano, onion, salt, garlic powder and cook for 3 minutes before adding the chorizo sausage. Brown all for about 5 minutes more.
If very oily, depending on sausage, drain sausage and vegetable mixture. Remove from pan and set aside.
Cube cheese(s) and place on bottom of the skillet or oven ready pie baking dish. Top with sausage vegetable mixture and bake for 10 minutes. Cheese should be melted and bubbling. Serve with tortilla chips.
Notes
Traditionally, to keep this authentic, if you can find queso de Oaxaca use 12 ounces of that instead of the 3 different cheeses listed here. It's a firm Mexican cheese that is slightly salty and melts similar to mozzarella.
