Not at all, most of these outlets, fry their chaaps before putting them on a stick and making it ‘tandoori’, surprising but true. And after they are roasted in tandoor, they add generous amount of ghee / butter / cream along with masala and chutney. Though I do not mind masala, however the added fat just kills any chance of these things being good for health. Do they taste good? A big Yes, however we should not eat them thinking that they good for health.
So my advice, if you are mood for Tandoori Soy Chaaps, because you want to eat healthy, check if they have fried them or not, and ask them not to garnish them with Ghee or butter, or if you want, you can ask them to keep it at minimum.
