Roll each breadstick into a long rope about 1/2-inch thick and 13+ inches long. Then sprinkle some garlic salt and shredded parmesan onto your work surface and roll the breadstick into the toppings to coat the stick, leaving the ends bare for the next step.
Pinch the ends together tightly creating a tear drop shape. Then pinch the top of the rounded end into a point, facing the same direction as the bottom point, creating a heart shape. Press more cheese and garlic salt into any bare areas of the heart. Repeat with each roll.
Place the heart shaped breadsticks onto a silicone lined baking sheet about an inch apart alternating directions to fit them all on one tray. Cover with greased plastic wrap and allow to rise for 30 to 45 minutes.
Beat an egg and brush it on top of the risen breadsticks. Bake at 350 degrees Fahrenheit for 15 to 18 minutes or until golden brown. Brush the tops with butter and serve warm.
