It's not easy making vegetarian pancit luglug but I tried anyway using tofu puffs and just 1 tablespoon of fish sauce for flavoring. I didn't use soy sauce as it will alter the taste of this Filipino dish. With other seasonings, boiled eggs, green onions and calamansi, puede na, it's not bad, I really like it. It's very light I had a large serving. It's a good thing our Philippine grocer sells these frozen calamansi in individual packets, very convenient. I can do without prawns and chicharon but not without calamansi and patis.
