First, make the sauce. In a small blender, add all of your ingredients for the sauce. Blend until completely smooth. Set aside.
Next, make the meatballs. In a large bowl, combine all of the ingredients. Roll them into balls, forming 24 large meatballs—or you can make them bigger or smaller, depending on your preference. If your meat is sticky, just wet the palms of your hands.
For air fryer—400F for 12 minutes. Depending on your air fryer basket size, you will likely need to work in batches.
If using the oven, line a baking sheet with parchment paper and bake at 400F for 25-30 minutes or until they are cooked through (165F internal temperature).
To make the pickled cucumbers and onions, slice the cucumbers and onions very thin. Add to a bowl and toss with rice vinegar and a pinch of salt.
Now serve your meal as desired.
