Beet
From Memory Alpha, the free Star Trek reference.
A beet is a plant with an edible root structure native to the planet Earth. The roots of beets are reddish in color with a strong flavor and most Humans consider them an acquired taste.
Benjamin Sisko insisted that beets were a "misunderstood vegetable" and that anyone who didn't like them simply hadn't eaten any that were properly prepared. (DS9: "Equilibrium")
