Mix vegetable kadai

If my husband is asked to place an order at the restaurant, he will blindly order for a mix vegetable kadai with tandoor roti and salad. Then he will ask the rest, whether they would like to have the same or something else. I have no clue on his fascination for this dish. I have now kind of given up on this.
I tried making it at home initially with loads of oil and ghee to emulate the taste. However, if it is made at home it should be healthy (Strange!) is what he says. So then, I asked him,  do not complain that it does not taste like the one we order from outside. 
Between this jugal bandi(verbal duel) we have settled for this version.
