In a mixing bowl put gram flour, yogurt, salt, finely chopped vegetables ( onion, red bell pepper, yellow bell pepper, capsicum, French beans, carrot), all the spices ( coriander powder, red chilly powder, turmeric powder, cumin seed), freshly chopped coriander leaves, pinch of soda.
Now add water as required and mix it well to make a medium thick and smooth batter. The batter should not be very thick or thin. Make sure there should not be any lumps in the batter.
To make besan toast take nonstick pan and heat pan on medium heat, spread little oil all around.
Once pan gets heated take one slice of brown bread (I have used brown bread you can use white bread also) and spread 2 tbsp of bean mixture onto one side of bread and place the besan mixture side onto the pan and toast it for few minutes from downwards.
Now spread the mixture on top of the bread and flip it over.
Now spread little oil all around the edges and let it cook from some time or until bread comes off easily from the pan.
Once both the sides turn golden brown, take out the besan toast from the pan and repeat the same process to make rest of the besan toast.
Cut besan toast into half and serve hot with any green chutney or tomato ketchup.
You can also dip the slices into the batter and then toast.
