Judi Pav might be a regional or local dish not widely known beyond a certain area. Based on your description, it sounds like a flavorful and delicious dish made with coconut, tomatoes, and onions, possibly served with pav (a type of bread roll popular in India). The combination of coconut and savory ingredients like tomatoes and onions likely creates a unique and tasty experience. If it has gained popularity after my knowledge cutoff, I may not have specific details about it. If you have any other questions or need information on other dishes, feel free to ask!
