First, make burger patties: in a medium bowl, combine all ingredients for the burger patties minus the turkey, only using half of the taco seasoning packet.
Fill a ziploc bag with the tortilla chips, seal, and smash into small crumbs. Place ground turkey and tortilla chip crumbs into same bowl as mixture and combine, making sure to not overmix. Mixture should be sticky but firm.
Divide the bowl into four and shape each 1/4th of the mixture into a patty; place onto a sprayed cookie sheet. Sprinkle second half of seasoning packet onto the top of the four patties.
Heat a grill pan over medium heat and brush with oil. When hot, place patties onto pan, making sure to not move once they are set (this will form your grill marks!). Cook for about 5-6 mins each side or until they are nice and charred.
To build your burgers, start with your toasted hamburger bun, then burger patty, then cotija cheese and/or guac. Finish off with fresh jalapeños, cilantro and another toasted bun!
