In a pan over medium heat, heat the olive oil. Sauté the ground beef, corn kernels, and garlic with the taco seasoning and a pinch of salt until browned, about 3-5 minutes.
Arrange the tortilla chips on a large sheet pan and cover with the ground beef and corn mixture, then sprinkle the shredded cheese on top. Place in the oven to bake for 5-8 minutes, or until the cheese is melted.
Remove from the oven and top with diced tomato, red onion, avocado, jalapeños, and cilantro.
