Step 1

Preheat oven broiler, and set the oven rack about 6 inches from the heat source.

Step 2

Heat the butter and olive oil in a skillet over medium heat, and pan-fry the chicken breasts for about 10 minutes per side until no longer pink on the inside and golden brown on the outside, sprinkling each side with Creole seasoning.

Step 3

Scoop the avocados into a bowl, and mash them with the lime juice, tomato, onion, garlic powder, salt, and pepper.

Step 4

Spoon about 1/3 cup of guacamole onto each chicken breast, top with a slice of pepper jack cheese, and broil for 2 to 4 minutes, until the cheese is melted and bubbling.
