Preheat oven to 425°F and lightly oil a large baking sheet with vegetable oil or another neutral flavored oil.
In a medium bowl, combine mayonnaise, sour cream, honey, soy sauce, and sriracha. Whisk well and set aside.
In a large bowl, combine pork and turkey, ginger, sliced green onion, panko, soy sauce, and salt. Mix well and form into 2-inch meatballs. This should make about 28.
Place meatballs on the prepared baking sheet. Roast in the oven for 15-17 minutes until meatballs are nicely browned.
Remove from oven. Either add meatballs to the bowl with sauce to coat or spoon sauce over for serving.
