In a medium bowl, combine ground chicken, breadcrumbs, onion, parsley, ginger, hot sauce, salt and fresh-ground pepper to taste. Mix well to incorporate. Shape into 16 equal-sized meatballs about 1-1/4 inches round.
Place on a lightly greased baking sheet and bake for 20 minutes.
While the meatballs are baking, in a small saucepan, warm butter, add the garlic and saute 30 seconds to 1 minute Add the crushed pineapple, and orange juice concentrate. Bring to a boil, soften the cornstarch in a little cold water and stir into boiling liquid. Stir while simmering until the mixture becomes syrupy. Remove from the heat and cool slightly.
