01 - Preheat oven broiler. Arrange red bell peppers on a baking sheet and broil, turning occasionally, for approximately 10 minutes until skins are charred and blistered. Transfer peppers to a bowl, cover, and allow to steam for 5 minutes. Peel off skins, remove seeds, and chop peppers.
02 - In a large pot, warm a splash of oil over medium heat. Add diced yellow onion, carrot, celery, and jalapeño (if using). Sauté for 5 to 6 minutes until vegetables are softened.
03 - Incorporate minced garlic, smoked paprika, cumin, chili powder, and oregano. Cook for 1 minute until spices are fragrant.
04 - Add chopped roasted peppers, drained black beans, diced tomatoes with juices, bay leaf, and vegetable broth. Stir thoroughly to combine.
05 - Bring mixture to a boil. Reduce heat and simmer uncovered for 25 to 30 minutes, stirring occasionally.
06 - Remove bay leaf. Using an immersion blender, partially blend the soup directly in the pot for a creamier consistency, or transfer 2 cups to a blender, puree, and return to the saucepan.
07 - Adjust seasoning with salt and black pepper to taste. Serve hot, garnished with fresh cilantro, lime wedges, and avocado as desired.
