Add the turkey, onion, chili powder, garlic power, salt, coriander, cumin and pepper to a bowl and stir until combined. Shape the mixture into 4 burgers and refrigerate for 30 minutes.
Heat the oil in a cast-iron skillet over medium-high heat. Add the burgers and cook for about 5 minutes; flip and cook until the internal temperature registers 165 degrees F, another 4 to 5 minutes, topping the burgers with the cheese in the last 2 minutes.
Transfer the burgers to the buns and top with tortilla chips, pickled jalapenos, pico de gallo and guacamole.
