On average, one person can eat about 3-4 mozzarella sticks per sitting. This can alter based on the size of the mozzarella sticks, as some might be larger in diameter than others.  Furthermore, the amount of cheese may also determine how many mozzarella sticks can be eaten in one sitting - for example, if each stick contains more cheese, then less may be able to fit into a single person's stomach!  Additionally, depending on the individual's appetite and preference level for mozzarella sticks, it is possible to consume more or fewer than the aforementioned range.
