Xerophagy

Xerophagy ("dry eating", from Greek ξηρός "dry" and φαγεῖν "eat") is the practice of eating dry food, especially food cooked without oil. In Eastern Christianity, xerophagy is the form of fasting observed during Great Lent and certain other fasts, in which vegetables cooked with water and salt are eaten, together with such things as fruit, nuts, bread and honey.
