In a mixing bowl, combine the shredded chicken, buffalo sauce, garlic powder, Greek yogurt, and a pinch of salt and pepper. Stir until everything is well mixed and the chicken is evenly coated.
Heat a large skillet over medium heat and add a drizzle of avocado oil. Allow the oil to warm up for a minute or two.
One at a time, brush both sides of the corn tortillas with avocado oil. Place them in the skillet and cook for about 30 seconds on each side or until they become lightly golden and crispy. Remove them from the skillet and set aside.
Once your tortillas are crispy, it’s time to assemble the tacos. Place a generous scoop of the buffalo chicken filling in each tortilla, followed by a sprinkle of shredded cheddar cheese.
Return the filled tacos to the skillet, and cover with a lid. Allow them to cook for an additional 2-3 minutes until the cheese is melted and bubbly.
Remove the tacos from the skillet and top them with shredded lettuce, guacamole, pickled red onions, and a drizzle of jalapeño ranch and extra buffalo sauce.
