Ash Reshteh, made with herbs, legumes, and noodles is the most popular & famous "thick soup" across all regions of Iran, especially during winter. It is also one of the main dishes of Norooz (Persian new year - starts 20-21st march). It is very similar to the Italian Minestrone.
Barbari is my favorite Persian bread, but I like it sans poppy seeds. This is delicious with yogurt or feta or butter or basically anything...and is really good as a pizza crust, too. Also this is a good recipe!
