Season the beef, chicken and pork with Sazon, adobo, garlic powder, oregano, pepper, onion powder, and chicken bouillon. Let it marinate for at least 30 minutes.
Heat oil in a large caldero over medium heat, then sauté the sofrito, tomato sauce, and Sazon, stirring with a wooden spoon.
Start by adding your tougher meats to the pot (Goat, Pork, Ribs, Oxtail etc). Sear the meat on high heat for 4-5 minutes and flip.
Then, pour chicken broth into the pot, ensuring the liquid just covers the meat. Cook over medium-low heat for about 45 minutes or until the beef and pork are fork tender.
Next, add yuca, corn, green plantain, malanga, yam, carrots, potatoes, bay leaf, and cilantro. Add more water if needed to ensure all meat and veggies are covered. Cook on low heat for 1 hour.
Add pumpkin (calabaza) and chicken. Add more liquid as needed so the meat is covered. Let the sancocho simmer on low heat for another 45 minutes, or until all the vegetables and meat are tender. The pumpkin should be so soft that it absorbs into the soup, giving it a bright yellow color.
Check the seasoning and adjust as needed. Add more salt or adobo if needed.
Serve with white rice.
