In a small bowl, toss the finely diced avocado with the fresh lime juice. This adds flavor and prevents the avocado from turning brown.

In a large mixing bowl, add the ground turkey, the avocado mixture, minced red onion, chopped cilantro, garlic powder, cumin, sea salt, and black pepper.

Using your hands or a fork, gently mix the ingredients together until just combined. Be careful not to overmix, as this will make the burgers tough.

Lightly wet your hands with cold water to prevent sticking. Divide the mixture into 4 equal portions and shape them into patties about 3/4-inch thick. Press your thumb gently into the center of each patty to create a small dimple (this keeps them flat while cooking).

Heat the olive oil in a large skillet over medium heat (or preheat your grill to medium-high). Cook the burgers for 5-6 minutes per side, or until a meat thermometer inserted into the thickest part reads 165°F (74°C).

Remove the burgers from the heat and let them rest for 2-3 minutes. Serve on buns or lettuce wraps with your favorite toppings!
