Mix well and keep aside.
Next, prepare the batter. In another bowl, mix together gram flour (besan), rice flour, carom seeds (ajwain), salt, and Kashmiri red chilli powder. Add in water and mix into a smooth batter. Let it rest for a while.
To prepare the pakodas, take 4 slices of bread. Spread green chutney generously on all the slices.

In the meantime, heat oil for deep frying.
Dip the prepared sandwich into the batter and wipe off the excess.
Deep fry on high heat till lightly colored.
