Step 1

Heat olive oil in a large pot over medium-low heat; add onion, garlic, cilantro, white pepper, oregano, and salt. Cook and stir until onion is browned and very tender, about 20 minutes. Add stew meat; cook and stir until meat is browned on all sides, 5 to 7 minutes.

Step 2

Pour enough water over meat mixture to fill pot 3/4 full; add tomato sauce and beef bouillon.

Step 3

Mix green beans, carrots, celery, chayote squash, white beans, cabbage, green banana, yellow plantain, llautias, potatoes, pumpkin, corn, and green bell pepper (in this order), cooking and stirring after each addition. Cook until all the vegetables are tender and stew has formed a rich broth, 2 to 3 hours. Add more water or salt if needed.
