Chop the meats into 2-inch chunks or smaller if desired and marinate with the adobo.
In a large pot, over low-to-medium heat, combine the oil, sofrito, chicken, and beef, and stir until the meat is brown on all sides. Add a bit of broth if the meat starts to burn or stick to the bottom.
Add the sazón, tomato sauce, broth, green olives, and all the root vegetables, including the green bananas, plantains, carrots, and corn.
Add additional broth or water if needed until everything is covered.
Bring to a boil. Lower to a simmer and cover for 30 minutes.
Uncover and simmer for 20 - 30 minutes or until the stock has reduced, the meat is tender, and the vegetables are soft.
Serve and sprinkle cilantro on top if desired.
Can be served with rice or on its own as a hearty soup. Enjoy!!
