Mozzarella.
McDonald's is under fire from customers accusing the burger chain of serving mozzarella sticks that are missing a key ingredient: cheese.
Customers are posting pictures of hollowed-out mozzarella sticks online and accusing the burger chain of serving them "fried air."
McDonald's launched mozzarella sticks nationwide this month as part of a new "McPick 2" promotion, which allows customers to pick two of the following for $2: a McDouble, a McChicken, small fries, and mozzarella sticks.
The mozzarella sticks are also available on their own, costing $1 for three sticks.
