Finely dice the chicken thighs into very small, pea-sized pieces to ensure even cooking and a cohesive fritter texture.
In a medium mixing bowl, whisk the egg until smooth, then add the diced chicken, corn kernels, sliced green onions, coconut flour, garlic powder, sea salt, and black pepper.
Stir the mixture thoroughly until the coconut flour has absorbed the moisture and the ingredients are well combined.
Heat the avocado oil in a large non-stick skillet over medium-high heat until shimmering.
Scoop the mixture into the skillet to form three or four equal-sized patties, pressing down gently with a spatula to flatten them to about half-inch thickness.
Cook for 4 to 5 minutes on the first side until a deep golden-brown crust forms.
Flip the fritters carefully and cook for an additional 4 minutes, or until the chicken is fully cooked through and the centers feel firm.
Remove from the pan and serve immediately while the edges are perfectly crispy.
