Hi there, here's my suggestion. Its very quick and easy and has 2syns on EE not sure about the others.
1 tin of chick peas - I have tried all the makes and Napolina brand is the best and yes you can taste the difference!
1 large potato - Microwave and dice to about the same size as the chick peas, keeping the skin on. Boil it if you prefer but with the microwave there is less washing up!
Some cucumber sliced (not to thin but not to thick either) and diced up smallish. I usually use 8 slices.
2tbsp of Tamarind Paste - Tesco and Sainsburys sell it by Bart
Chaat Masala - It comes in a box not a jar and is available in Tesco in the "Asian Area" Add this a sprinkling at a time, keep tasting as you add so its not to hot. I usually add 2dsp so maybe start with 1dsp.
This is a fast Indian Savory dish, I hope you like it... I'm addicted to it

you can also add the Chaat Massala to fruit salad to spice it up, I know it sounds funny but its really nice xx
