Every week at Stone's Throw, we break off a piece of bread (trying not to pick the spot that results in you taking half of the loaf for yourself) and dunk it in some grape juice (trying to make sure you aren't the guy whose finger touches the juice, disrupting the holiness of the event for everyone in line). In this passage, we see the introduction of that practice. In the parallel account in Luke 22, we see Jesus command us to do this when we gather in remembrance of him. When we take communion each Sunday, the truths of this passage should enter our minds as we remember Jesus.
