This is a easy, fool-proof recipe, handed down by my mom who was a wonderful cook. I try my best to recreate her awesome dishes.
Heat the olive oil in a large soup pot over medium heat, and brown the oxtails and beef stew meat on all sides. Add water to cover the meat, bring to a boil, reduce heat to a simmer, and cook for 30 minutes. Skim off and discard any foam that collects at the top.
Drop in the bouillon cube, onion, celery, chili powder, cumin, salt, pepper, and corn ears, stir to combine, and simmer the soup until the meat is very tender, about 2 hours. Stir in the carrots and potatoes, simmer for 30 more minutes, then stir in the lentils, rice, mixed vegetables, and cabbage. Simmer until the rice, lentils, and cabbage are tender, about 30 more minutes. Serve with a half ear of corn in each bowl, with hot steamed tortillas for dipping in the broth.
