Soak the dried pepper in ¼ cup of warm water in a bowl for about 6 to 8 minutes. Place a spoon or something on top so it gets submerged under the water. Once it's much softer, de-stem and de-seed and place in a food processor.
In a cast-iron pan over medium heat, add olive oil and sauté red onion and garlic for about 3 to 4 minutes until softened and fragrant. Stir in smoked paprika and cook for another minute. Add canned refried beans and ½ cup fire roasted tomatoes (with the liquid) and stir to combine until warmed through, about 1 to 2 minutes. Add the mixture to the food processor with the dried pepper and process until mostly smooth but still has some texture and the pepper is flecked throughout.
It should be warm enough to serve. Otherwise reheat for serving, add to a bowl and top with chopped red onion, cilantro, vegan cheddar shreds - or other garnishes of your choice
