In a large pot, add the red beans and water. Bring to a boil and then reduce the heat to a simmer. Cook for about 1 hour, or until the beans are tender.
In a separate pan, heat the vegetable oil over medium heat. Add the chopped onion and bell pepper, and cook until the vegetables are soft and translucent.
Add the minced garlic to the pan and cook for an additional minute.
Add the chopped tomatoes, cumin, oregano, salt, and pepper to the pan. Cook for about 5 minutes, or until the tomatoes have softened and released their juices.
Add the tomato mixture to the pot with the beans and stir to combine. Cook for an additional 10 minutes to allow the flavors to meld together.
Serve the soup hot, garnished with chopped cilantro and lime wedges.
