Spread an even layer of hummus across one piece of lavash, leaving about an inch margin on all four sides.
Spread 1/4 of the lentils over the hummus.
Sprinkle 1/4 of the olives onto the lentils. Then add an even layer of arugula.
Fold over the bottom end of the lavash about 2 inches up. Then roll the rest of it from one side to the other, leaving the top open. (If you haven’t over-filled it, you could fold over the top end as well, but I always put too much filling in for this)
