1. First make the broth base. I sauteed onion, carrots, celery, and garlic until soft. Then I added 1 large container of beef broth($2) and 1 large can of dice tomatoes ($1) and 1 small can of corn (50cents). Let simmer.
2. I took ~1/2 very lean ground round ($2) and added some diced onion, cilantro, 3 Tbsp uncooked rice, 1 egg and salt and pepper. (You could have used a pound of ground beef to 1/3 cup uncooked rice). Round into meatball shape.
3. Place meatballs in hot vegetable stock and simmer until meat is done. Spiced it up with a little chili powder and cumin powder. Add salt and pepper to taste and even hot sauce or jalapenos as your desire.
Muy Delicioso!
As a nutritionist, this is a soup packed full of vegetable like carrots with beta carotene and fiber from the rice and corn. You could use brown rice for more fiber. You could add more fiber and protein (or make it vegetarian) by adding garbanzo beans with is traditionally found in Mexican soups.
