Preheat the oven to 375°F.
Heat the vegetable oil in a large skillet over medium high heat. Cook the beef until browned and cooked through, about 3-5 minutes. Remove and set aside.
Using the same skillet, stir fry the kimchi with sesame oil and sugar for about 3-5 minutes. Set aside.
Place tortilla chips in an even layer on a lined baking tray with nonstick cooking spray. Top with the cheeses and bulgogi. Bake in the oven for 5-7 minutes, until the cheese has melted.
Remove from the oven, and top with the kimchi, gochujang mayo, guacamole, toasted sesame seeds, green onion and cilantro. Enjoy immediately!
