Mast o khiar is a simple and refreshing Iranian dip made with yogurt and diced cucumbers. In its original form, it is generously seasoned with mint, but it can be easily adapted with other ingredients such as garlic, walnuts, raisins, and various herbs and spices.

Served chilled, mast o khiar is a staple side dish of every Iranian meal but also a quick and nutritious snack when accompanied by crispy flatbreads.
