How to Make It
Preheat oven to 400°F. Heat the oil in a large skillet over medium heat. Add the scallions, garlic, chili powder, cumin, and salt and cook, stirring occasionally, until softened, about 3 minutes. Add the beef and cook, breaking up with a wooden spoon, until browned, about 5 minutes. Stir in the green chiles.
Combine the cheeses in a small bowl. Line the cups of a muffin tin with tortilla chips, breaking to cover bottom and line sides. Divide ⅓ of the cheese mixture among cups. Divide ½ of the beef mixture among cups and top with half of the remaining cheese mixture. Top with remaining beef mixture, and finish with cheese. Bake until the cups are heated through, cheese is melted, and the edges are browned, 9 to 11 minutes.
Just before serving, top each cup with diced avocado, sour cream, pico de gallo, pickled jalapeños, and fresh cilantro.
