3/4 cup white rice
1-1/2 cups water
2 onions, diced
1/2 lb ground pork
1/2 lb ground beef
1 egg
1 tsp ground cumin
1 tsp dried oregano
1 garlic clove, minced
1 zucchini, diced
2 carrots, diced
2 tomatoes, diced
6 cups chicken stock

Bring the water to a boil and pour it over the rice. Let soak for 30 minutes, then drain; set aside. Saute one of the onions until soft, about 5 minutes. Combine the pork, beef, cooked onion, rice, egg, cumin, oregano, and salt and pepper to taste. Mix well and form into 1" balls. Saute the remaining onion until soft; add the garlic, zucchini, carrots and tomatoes and cook about 5 minutes. Add the chicken stock, stir well and bring to a boil. Carefully drop the meatballs into the soup. Reduce heat and simmer, uncovered for about 45 minutes or until the meatballs are fully cooked. Serve with fresh chopped cilantro on top.
