Lightly grease a prepared baking sheet and set aside. On a lightly floured work surface, separate 12 breadsticks and allow them to thaw until pliable. Place one breadstick garlic-side up horizontally in front of you. Starting from the left end, tightly roll the dough toward the center. Repeat from the right end so both rolled ends meet in the middle, creating the top of the heart.

Transfer the shaped dough to the prepared baking sheet and pinch the bottom of the dough together to form the point of the heart. Repeat with the remaining breadsticks. Allow the shaped breadsticks to rise in a warm place until puffy.

Bake in a preheated 325 degree convection oven for 7 to 10 minutes, or until lightly golden brown. Remove from the oven and serve warm with marinara sauce.
