Nice! Sounds like great quality (: This small amount, but still enough flavour, reminds me of good, fragrant homemade GM!
It's still somehow traditional, but not a chaat item per se, very easy to do and you will get a good taste of that masala - what about some sandwich? ;P I was thinking about the Bombay Sandwich, but you can make any sandwich you like, and spice it up with that Chaat. In fact, Chaat masala is pretty similiar to what they call "Sandwich masala" over there, just with a few more spices - and many sandwich vendors prefer it!
Salads, raitas, fingerfood... any BIR dish that needs a sour taste or pakistani food (almost anything "Lahori style") - there has to be something for you (:
