Stuffing was a mixture of ingredients that served as a filling for a hollow food item.
Benjamin Sisko served stuffing in a Thanksgiving dinner on Deep Space 9 in 2372. A year later, Michael Eddington told him that he believed the captain had added too much tarragon to it. (DS9: "Blaze of Glory")
Fried oysters served at Sisko's Creole Kitchen were stuffed prior to being fried. (DS9: "Paradise Lost"; LD: "Grounded")
