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.
