In a medium bowl, combine the ground chicken, garlic powder, onion powder, sea salt, and black pepper until just mixed.
Form the mixture into two equal-sized patties, pressing a small indentation into the center of each to ensure even cooking.
Heat the extra virgin olive oil in a grill pan or cast-iron skillet over medium-high heat.
Place the patties in the pan and cook for 5 to 6 minutes per side, or until the internal temperature reaches 165°F and the exterior is golden-brown.
While the chicken is grilling, rinse the butter lettuce leaves and pat them completely dry to maintain a crisp texture.
Thinly slice the avocado, red onion, and tomato.
Stack two lettuce leaves together for each wrap to create a sturdy base.
Place one cooked chicken patty onto each lettuce stack and top with the avocado, red onion, tomato, and a dollop of Dijon mustard.
