In a large gallon sized zip top bag or an airtight container, add avocado oil, lime juice, chipotle powder, smoked paprika, garlic salt and kosher salt. Stir to combine. Using a zip top bag holders, makes this task a breeze.
Next add the thinly sliced chicken breasts to the marinade ingredients. Gently mix the marinade so that it covers the chicken, evenly.
Place the bag or container in the refrigerator for at least 30 minutes but no longer than 24 hours.
Preheat the grill to medium heat. If grilling is not an option, use a grill pan on the stovetop. Place a tablespoon of vegetable oil or avocado oil on a folded paper towel. Using tongs holding the paper towel, grease the grill grates.
Using tongs, remove the marinated chicken and place on the grill grates. Shake off an excess marinade to help prevent flare ups.
Grill the chicken for 5-8 minutes or until there is a good sear on one side. Flip and cook again for 4-6 minutes or until the chicken reaches an internal temperature of 165 degrees F is reached.
Using clean tongs, remove the chicken breasts and place on a baking sheet. Tent with tin foil and allow the chicken to rest for 10 minutes.
Next lightly butter the hamburger buns and toast until golden brown. Then build the ultimate chipotle chicken sandwich. Add lettuce leaves, grilled chicken breast, chipotle mayo, a slice of pepper jack cheese, tomato slice, a scoop of guacamole and the top bun.
