Heat the vegetable oil in a large pot over medium heat. Add the beef or goat meat and cook until browned on all sides, about 5-7 minutes. Remove the meat from the pot and set aside.
In the same pot, add the chopped onion and cook until translucent, about 3-4 minutes. Add the minced garlic and cook for an additional 1 minute.
Stir in the chopped tomatoes and bell pepper. Cook for 5 minutes until the tomatoes start to break down.
Return the browned meat to the pot. Add the beef or vegetable broth, ground cumin, paprika, dried thyme, and salt and black pepper. Bring to a boil.
Reduce heat to low, cover, and simmer for about 30 minutes, or until the meat is tender.
Add the sliced green plantains to the pot. Continue to simmer for an additional 15-20 minutes, or until the plantains are cooked and tender.
Taste and adjust seasoning with salt and black pepper. Add sliced hot peppers for extra heat if desired.
Garnish with chopped fresh cilantro before serving.
Enjoy your meal!
