Bring 10 cups water to a boil over high heat in a large Dutch oven or stockpot. Add the escarole, and reduce heat to medium. Cook for 10 minutes or until tender; drain well.
Heat oil in pan over medium heat. Add garlic; cook for 3 minutes or until lightly browned. Stir in 1/2 cup water, crushed red pepper, black pepper, cannellini beans, and soup. Bring to a boil; add cooked escarole, and cook until thoroughly heated. Ladle into individual bowls, and sprinkle with cheese.
NOTE: One (10-ounce) package of frozen chopped spinach that has been thawed, drained, and squeezed dry (about 1 1/4 cups) can be substituted for escarole or fresh spinach.
