Heat oil to 375 degrees. Let dough thaw until pliable. Slice each Bridgford Demi-Loaf into 3 pieces. Using a small amount of flour on hands, gently stretch each dough piece into large circles, 7 inches in diameter. To fry dough, place in hot oil, turning once, until both sides are golden brown. Blot oil with paper towels. Layer with beans, cheese, tomatoes, and lettuce. Top with sour cream and olives.
