In a medium mixing bowl, combine the drained canned chicken, room-temperature cream cheese, chopped onion (or onion powder), garlic powder, kosher salt, and 1/2 cup of the chopped pecans; stir until evenly mixed.
Place a large piece of plastic wrap on the work surface and spoon the mixture into its center.
Using the plastic wrap, gather the edges and press the mixture into a tight ball, twisting the wrap to compact it.
Unwrap the ball and roll it in the remaining chopped pecans, pressing gently so the nuts adhere to the surface.
Re-wrap the coated cheese ball in plastic wrap and chill in the refrigerator for at least 1 hour (can be refrigerated up to 3 days) before serving.
Serve the cheese ball with crackers and fruit.
