What about vegetarian street food ( sans eggs,meat,pork,seafood) in BKK ?
Only on request a kind lady near Sathorn
road specially prepared a veg fried rice and spinach soup for us.
Even the Tomato soup had some extact of fish oil in it.
They have great veg restaurants at the back of Burger King, Khao san road. As for street food, the green mangoes, oops you cant eat fish, so you cant have the PAPAYA SALADS.... the fried noodles, I hate it, coz I see them frying the eggs on the wok.
