In a medium bowl, whisk to combine onion, garlic, parsley, egg and water.
Add ground beef, 2 ½ cups cooked Uncle Ben’s rice, salt, pepper and allspice into the bowl and mix well with your clean hands.
Shape meat into 1 ½ to 2 inch balls (about golf ball size) and arrange in a lightly greased 8×8 baking dish.
In a small bowl, mix together sauce ingredients. Pour over top of meatballs and cover with foil.
Bake for 20 to 25 minutes* or until cooked through.
Notes
Check meatball temperature with a meat thermometer to ensure they are cooked. We had to leave ours in about 20 minutes longer than the original recipe to reach the proper temperature.
