Stephen Goranson suggests that Judah the Essene, mentioned by Josephus, is the Teacher. 
Essene bread is a very primitive form of sprouted grain bread.
It is often eaten uncooked, or slightly heated, by proponents of raw foods.
The Essenes, a Jewish religious group that flourished from the 2nd century BC to the 1st century AD, are credited with the technique and basic recipes for Essene bread, which is made from sprouted wheat and prepared at a low temperature.
These two practices ensure the maximum possible vitamin content for this foodstuff.
The sprouting also breaks down the lectins and other substances that some individuals may be sensitive or allergic to.
The following is an excerpt from "The Essene Gospel of Peace", as translated by Edmund Bordeaux Szekely. 
Teralfene is a village which makes part of the municipality Affligem, together with Hekelgem and Essene.
It has an area of 244 ha (602.94 acres) 
According to a Jewish legend, one of the Essenes, named Menachem, had passed at least some of his mystical knowledge to the Talmudic mystic Nehunya ben HaKanah, to whom the Kabbalistic tradition attributes Sefer HaBahir and, by some opinions, Sefer HaKanah, Sefer HaPeliah and Sefer HaTemunah.
Some Essene rituals, such as daily immersion in the mikveh, coincide with contemporary Hasidic practices; some historians have also suggested that the name "Essene" is a Hellenized form of the word "Hasidim" or "Hasid" ("pious ones").
However, the legendary connections between Essene and Kabbalistic tradition are not verified by modern historians. 
According to later tradition, the Last Supper took place in what is called today The Room of the Last Supper on Mount Zion, just outside of the walls of the Old City of Jerusalem, and is traditionally known as "The Upper Room".
This is based on the account in the Synoptic Gospels that states that Jesus had instructed a pair of unnamed disciples to go to "the city" to meet "a man carrying a jar of water", who would lead them to a house, where they would find "a large upper room furnished and ready".
In this upper room they "prepare the Passover".
No more specific indication of the location is given in the New Testament, and the "city" referred to may be a suburb of Jerusalem, such as Bethany, rather than Jerusalem itself.
The traditional location is in an area that, according to archaeology, had a large Essene community, a point made by scholars who suspect a link between Jesus and the group (Kilgallen 265).
Saint Mark's Syrian Orthodox Church in Jerusalem is another possible site for the room in which the Last Supper was held, and contains a Christian stone inscription testifying to early reverence for that spot.
Certainly the room they have is older than that of the current coenaculum (crusader - 12th century) and as the room is now underground the relative altitude is correct (the streets of 1st century Jerusalem were at least twelve feet (3.6 metres) lower than those of today, so any true building of that time would have even its upper storey currently under the earth).
They also have a revered Icon of the Virgin Mary, reputedly painted from life by St Luke.
Bargil Pixner claims the original site is located beneath the current structure of the Cenacle on Mount Zion.
