Lunch Salad- black chick peas and potato

I have been trying to make filling salads and off late found some success. And for a person who started having slices of cucumber, tomato with salt and pepper; I guess I have made a bit of progress. So here's the newest lunch salad.

Soak 1 cup of black chick peas (kala channa) overnight. Drain the excess water.
Boil 2 potatoes and skin them. Chop these into 1cm * 1cm cubes
Cut 1 cucumber/ zucchini into small cubes.
Take 3-4 leaves of lettuce and chop them inch wide.
1 cup of Rucola ( this the most important. Soul o my salads)

Toss the ingredients along with 2-3 tbsp of Jogurt and 1 tsp of chaat powder.

Serve cold!
