Bring forth therefore fruits worthy of repentance, and begin not to say within yourselves, We have Abraham to our father: for I say unto you, That God is able of these stones to raise up children unto Abraham. And now also the axe is laid unto the root of the trees: every tree therefore which bringeth not forth good fruit is hewn down, and cast into the fire. And the people asked him, saying, What shall we do then? He answereth and saith unto them, He that hath two coats, let him impart to him that hath none; and he that hath meat, let him do likewise.
Luke 3:8-11

Here, "meat" refers to food in general again. Here, Christ is explaining that true repentance is evidenced in how we behave toward others around us, specifically, in a more generous, giving manner, including with our food.
