In a medium mixing bowl, combine the ground chicken, corn kernels, egg, almond flour, green onions, sea salt, black pepper, and garlic powder.
Mix the ingredients thoroughly with a spatula until the mixture is uniform and holds together.
Form the mixture into 3 or 4 even-sized patties, pressing them slightly flat to ensure even cooking.
Heat the olive oil in a large non-stick skillet over medium heat until the oil is shimmering.
Place the fritters in the skillet and cook for 5 to 6 minutes per side, or until they are golden brown and the internal temperature reaches 165°F.
While the fritters cook, prepare the crema by mashing the avocado with the Greek yogurt, lime juice, and cilantro in a small bowl until smooth.
Plate the warm fritters and dollop each with the creamy avocado mixture before serving.
