In a large pot, heat the vegetable oil over medium heat.
Add the chopped onion and cook until softened and translucent, about 5 minutes.
Stir in the minced garlic and chopped hot peppers, cooking for another 1-2 minutes.
Add the beef, chicken, or fish pieces to the pot. Cook until browned on all sides.
Stir in the ground pepper, paprika, ground cumin, ground coriander, dried thyme, salt, and black pepper.
Pour in the water or beef/chicken broth and bring to a boil.
Reduce the heat to low, cover the pot, and simmer for about 20 minutes.
Add the cubed potato and chopped tomatoes. Continue to simmer for an additional 20-25 minutes, or until the meat and potatoes are tender.
Garnish with chopped fresh cilantro or parsley.
Enjoy your meal!
