Lay the lavash flat and spread a thin layer of hummus over one half.
Pull the Armenian string cheese into thin strands and scatter them over the hummus.
Sprinkle the Aleppo pepper over the cheese.
Fold the lavash over to close it.
Melt the butter in a large skillet over medium to medium-low heat.
Add the folded lavash and cook until golden and crispy on the bottom, about 2 to 3 minutes.
Flip and crisp the other side until golden and the cheese is melted, about 2 to 3 minutes more.
Slice and serve warm.
