Soak dried beans in water to cover overnight. Drain beans.
Heat oil in large saucepan over medium heat. Sauté onions, celery, bell pepper and garlic for 7 to 10 minutes, or until soft. Add drained beans. Add enough water to cover beans, and bring to a boil. Add bay leaves.
Reduce heat to low, and cook, stirring occasionally, about 2 hours. Add extra water if needed; don’t let beans dry out. Mash about half of beans against side of pot with spoon; leave remainder whole. Remove and discard bay leaves.
To serve, stir in parsley, hot sauce, salt and pepper. Spoon beans over or alongside rice, and garnish with sliced scallions.
