Step 1

In a small bowl, mix together, paprika, garlic powder, onion powder, black pepper, cayenne pepper, dried oregano, 1/8 tsp chipotle chili powder, smoked paprika and salt.

Step 2

Using a meat mallet or rolling pin, flatten chicken until it's about 1/4-inch thick. Cut each breast in half so you have 8 pieces. Season both sides of chicken with seasoning.

Step 3

Heat a cast-iron skillet or grill to a medium heat. Cook chicken about 4-5 minutes per side until cooked through. If using a cast-iron skillet, you may need to work in batches.

Step 4

While chicken is cooking, add mayo, lime juice, and remaining chipotle chili powder together in a small bowl. Season to taste with salt and pepper. Set aside.

Step 5

Once the chicken is cooked, top each breast with a piece of gouda. Add a couple teaspoons of water to the skillet and cover for 10-15 seconds until cheese has melted.

Step 6

Slather both sides of bun with mayo. Top with two pieces of chicken, followed by a slice of tomato and half of an avocado. Season avocado with salt and pepper. If using, top with onion straws.
