Roast chicken was a type of chicken dish prepared by roasting the meat.
In 2375, biomimetic lifeform copies of The Doctor and Neelix discussed Tom Paris and B'Elanna Torres's imminent wedding. Neelix asked The Doctor whether he was sure that the rice that would be thrown at the couple wasn't supposed to be cooked, steamed or fried. The Doctor replied that "The idea is to shower the couple with a symbol of good fortune, not garnish them like a roast chicken." (VOY: "Course: Oblivion")
