Masala Idli is a spicy and tangy variation of the classic idli. It is made by sautéing idli cubes with a tempering of mustard seeds, curry leaves, onions, and spices. The idlis are then tossed in a flavorful masala gravy, which coats them well. This dish is a great way to use leftover idlis and transform them into a delicious and filling snack or breakfast option. Serve masala idli with coconut chutney or tomato ketchup for a lip-smacking experience.
