In a medium bowl, combine finely diced cooked chicken breast, cooked chickpea pasta, shredded cheddar, parmesan, Greek yogurt, garlic powder, onion powder, salt, and pepper until well incorporated.
Form the mixture into four evenly sized, tightly packed balls and place them in the freezer for 10 minutes to set.
Prepare two small shallow bowls, placing the whisked egg in one and the panko breadcrumbs in the other.
Roll each chilled ball in the egg wash until fully coated, then dredge through the panko breadcrumbs, pressing gently to adhere.
Heat the avocado oil in a small non-stick skillet over medium-high heat until shimmering.
Carefully place the balls into the hot oil and fry for 2-3 minutes per side, turning carefully until every side is deep golden brown and crunchy.
Remove the balls from the skillet and let them rest on a paper towel for one minute before serving warm.
