Paruppu usili is a traditional south indian dish prepared with the goodness of dals. The dish is usually prepared using vegetables like french beans, cluster beans, cabbage, plantain flower. You can make this dish when you have less quantity of these vegetables. Since we include dal in this, it goes well with any kuzhambu or rasam variety without dal. This includes mor kuzhambu, vathal kuzhambu , kara kuzhambu or a simple rasam. My mother and aunty used to prepare this as an accompaniment for mor kuzhambu or vathal kuzhambu at least once or twice a month.
