Combine the onions, garlic, parsley, cilantro, spices, and salt with the ground beef. Mix well, then shape into meatballs.

Place the meatballs in a deep pan or baking dish with oil and brown them.

Once the meatballs are browned, add the canned crushed tomatoes and cook over heat until the sauce thickens slightly.

Add the strained tamarind to the meatballs and simmer over medium heat until the sauce thickens.

Once the sauce has thickened, remove from heat and serve with white rice.
