Creating the Cuban White Bean Soup is a simple process. Follow these steps to make this enriching soup:

1. Heat Oil: In a large pot, heat the olive oil over medium heat.
2. Sauté Vegetables: Add the diced onion, minced garlic, chopped carrots, chopped celery, and bell pepper. Sauté for about 5-7 minutes until the vegetables are soft.
3. Add Spices: Stir in the cumin, paprika, and crushed red pepper flakes. Cook for an additional minute until fragrant.
4. Pour in Broth: Gradually add the vegetable or chicken broth. Stir well to combine.

6. Bring to a Boil: Increase the heat to high and bring the soup to a boil.
7. Reduce Heat: Lower the heat to a simmer. Let it cook uncovered for about 30-40 minutes to allow flavors to meld and the soup to thicken.
8. Adjust Seasoning: Taste the soup and season with salt and pepper to your liking.
9. Finish with Lime: Just before serving, stir in the lime juice for a fresh burst of flavor.
10. Garnish: Ladle the soup into bowls and garnish with fresh cilantro or parsley.
