Soak semolina in half cup water. Set this aside for 20 mins.
Meanwhile chop the veggies and season the pan or tawa with oil. Wipe off excess with a kitchen tissue.
Stir in the yogurt and salt to the soaked rava. The consistency should be neither too thick not too runny. You need a medium consistency.
If the batter is too thick you may splash a bit of water - 1 to 2 tablespoons & stir. (Check pics in the post to know the consistency)
Heat the pan on a medium high flame. Drizzle a few drops of oil on the pan and smear with a kitchen tissue carefully.
When the pan is hot, pour half of the batter and spread a bit gently.
Sprinkle the veggies and press with a spatula.
Add oil or ghee around the edges and cook on a medium heat until you see the edges loosen from the pan.
Flip the uttapam carefully with a spatula.
Cook until the veggies are partially done or brown to your liking. Flip back and cook until the rava uttapam turns lightly crisp.
If you want you can also sprinkle some Podi or cheese. Serve rava uttapam hot or warm with chutney or masala tea.
