It’s not too difficult to eat out as a vegan, though finding healthy whole foods may be more difficult.
These are the easiest, because the vegetarian cuisines of Asian countries do not traditionally use milk. When you ask for vegetarian you will likely avoid dairy. But do check if the noodles or batter contain egg!
Most Indian vegetarian cuisine is vegan as long as you avoid ghee, butter, paneer and curd (yogurt). South Indian food has many vegan options (like dosa, idli, vada, rice dishes, sambhar, coconut chutney) but with North Indian food it’s more difficult. Naan contains egg unless you are eating in a vegetarian restaurant and many dishes contain dairy, so ask before ordering. Most Indian desserts are made with dairy and sugar.
The following street foods are vegan: paani puri, bhel puri, sev puri, ragda pattice (if not fried in ghee), samosa chole, chole bature, vada pav, samosa pav, misal pav, dhoklas (ask if curd has been added to the batter). Some indian vegan sweets include: soan papdi, jalebis (check if yogurt was added to the batter and/or it was fried in ghee), kaju katli
Italian restaurants often cook in olive oil so they too may be able to offer you something vegan by dropping the cheese. Salads are often a healthy vegan option. Breads sometimes contain milk.
With the demand rising for vegan food, a lot of cafes are offering non-dairy options. Fast food and burger joints are also catering to vegans
Bear in mind that to be a healthy vegan, you should avoid fast food and only indulge occasionally!
