The good news is that Iranian cuisine is superb. Fragrant rice (berenj) is the staple of Iranian food. Boiled and then steamed, it is often colored with saffron or flavored with a variety of spices. When served plain as an accompaniment, it is known as chelo. The two most common meat/chelo combinations are kebab variations (chelo kabāb) or rotisserie chicken (chelo morgh). The variety of options for vegetarians is less. Falafels and garden salads (sālād-e-fasl) and greengrocers are common. Most ash varieties are meat-free and filling, as are most variations of kookoo, the Iranian take on the frittata.
