Preheat oven to 400ºF. Line a large baking sheet with parchment paper and set aside.
Heat olive oil in a large skillet over medium-high heat. Add the ground beef, tomato paste, chili powder, ground cumin, salt, garlic powder, onion powder, paprika, and dried oregano.
Use a wooden spoon to break up the meat into smaller chunks. Cook, stirring occasionally, for 6-8 minutes, until beef is browned.
Layer ½ of the tortilla chips on the prepared baking sheet with ½ of the ground beef, ½ of the shredded cheese, ½ of the black beans, and ½ of the yellow corn.
Repeat to create a top layer with the remaining ingredients.
Bake in the oven for 4-6 minutes, until the cheese has just melted.
Top with desired toppings like tomatoes, pickled jalapeños, sour cream, red onions, cilantro, and avocado. Serve immediately.
