How to Make It
Make the queso fundido: Preheat a large skillet over medium-high heat. Crumble the chorizo into the skillet and cook, breaking the meat up with a spoon, until the meat is browned, 5 to 7 minutes. Add the onion and cook until softened, about 4 minutes. Add the salsa, lower the heat to medium and bring the mixture to a simmer. Cook until any liquid evaporates, 5 to 7 minutes. Add the cheeses and stir for 1 minute. Turn off the heat and continue stirring until all of the cheese has melted.
Scatter the chips on a serving platter. Ladle about half of the queso fundido over the chips. Spoon a cup or more of the avocado-tomatillo salsa around the pile wherever the queso didn’t land.
Sprinkle with the cilantro, tomatoes, onion and olives. Sprinkle the cotija cheese over the top. Serve with lime wedges.
