This sandwich is basically made with vegetable filling placed inbetween 2 slices of bread, then toasted in butter. Make the stuffing with vegetables sauted and spiced up with indian spices like red chilli powder and garam masala powder. I have used most common vegetables found in every indian kitchen like onion, capsicum and carrot. But the variations are endless. I have used mayo for binding else the filling will be dry and may fall apart while cutting.
