Preheat oven to 425℉ and line baking sheet with parchment paper. I used a jumbo sheet for this recipe.
In a skillet, heat 1/2 tablespoon of oil over medium-high heat. Add chicken, breaking up is it cooks until cooked through. Add taco seasoning and prepare with water according to package instructions.
Wrap stack of tortillas in damp paper towel and heat for 30 seconds to 1 minute, just until tortillas are soft. Arrange tortillas evenly on baking sheet and brush both sides lightly with remaining oil.
Divide ground chicken evenly onto one side of each tortilla, followed by cheese, and 1-2 tablespoons of salsa. Fold tortilla over and bake for about 15 minutes, or until cheese is melted and tacos are crispy.
Carefully open taco and add lettuce, diced tomatoes, fresh lime juice, avocado, and cilantro.
