In a large bowl, mix together the ground beef, bread crumbs, egg, onion, garlic, cumin, oregano, salt, and pepper until evenly blended.
Form the mixture into 1-inch meatballs.
Heat the olive oil in a large pot over medium-high heat. Add the meatballs and cook, turning occasionally, until browned on all sides, about 10 minutes.
Add the celery, carrots, potatoes, and chicken broth. Bring to a boil, reduce heat, and simmer for 30 minutes.
Add the green peas and simmer for an additional 15 minutes.
Stir in the chopped fresh cilantro and season to taste with additional salt and pepper, if desired.
