First you need dosa batter and you can learn on how to nail that recipe here. Either you can make it at home like I do or nowadays you even get homemade quality batter in the Indian grocery store which you can totally get! Transfer the batter to a mixing bowl. To that add chopped onions, tomatoes, boiled and chopped beets, minced green chillies, chopped curry leaves, chopped spinach and cilantro. Feel free to add in any more veggies that you like - cabbage, carrots, green peas, kale, cucumber, etc. Add salt and roasted cumin powder. Give the batter a good mix. Heat a pancake pan and pour a spoonful of this batter and cook it like a pancake evenly on both sides. Drizzle ghee/oil around it while cooking the uttapam. Make as many as you need and store the remaining batter in the refrigerator. Serve them warm.
