Strict vegan for three days in Polonnaruwa town — hoppers with egg only, or can rice-and-curry places cook without dairy?

You can eat well if you ask clearly: vegetable curry without ghee, dal without yogurt finish, rice, roti without butter, plain string hoppers without the egg hopper, fruit, and tea without milk. Say no egg, no milk, no curd, no ghee — smile, point, repeat. Many rice-and-curry places already cook vegetable pots separate from fish; the risk is the condiment tray. Tourist cafes are easier; town places are fine with patience. I will not invent a restaurant ranking. Carry snacks for long site mornings, and accept that fancy vegan cheese is not the local mission.
