Combine rice flour, wheat flour, all purpose flour and salt. Add water little at a time and mix. Knead slowly to form a semi stiff dough. Divide the dough in equal parts.

On a floured surface roll the dough in a thin circle with a rolling pin.

With a cutter, cut out circles in the dough. Remove the extra dough and add it to the unused dough. Prick each puri with a fork.

Gently slide 3 to 4 puris into the hot oil and fry till golden brown on both sides.

Drain on absorbent paper. Repeat with the remaining dough.

In a large bowl mix all the ingredients mentioned in the above list except boondi and keep it in a refrigerator for an hour or overnight which would be better. Add boondi just before serving and mix.

Fill a plate with puris. Top it with the avocado mixture.

Pop in your mouth immediately.

Enjoy.
