Sponge Dosa/ No fermentation

We do make much varieties with the Idli or Dosa batter in this part of the world (my home). There are some standard instant recipes for dosas but then they are not really dosas , they are ghavana.
My little one loves dosas and often eats them by rolling it into a wrap holding in one hand while cycling his 2 wheeler from one room to another. But..(the but, but!) , he is very particular about the taste. Unfortunately the fermented dosas become sour in the evenings so I have been avoiding it as an evening snack. This is when I came across the recipe for sponge dosa. I wanted to try this for long time but came around making it only yesterday. This has no bearing to the name of any of the recipes you are used to as I always have a spun off version,

Zucchini Pizza

Zucchini , cucumbers are refreshing eats for summers. I normally include zucchini in vegetable stir fry, pastas or chinese dishes. This time I tried making an exclusive pizza. Earlier the plan was to make a sandwich but the tiny nose was pulled up to make a frowning face.
I quickly rattled out a few options- noodles, pasta, soup, sheera, upma or pizza? Pizza word caught a smile and twinkle in the eyes.

Roasted tomato cheese sandwich

I had laid out the chopped tomatoes for sun drying. About a hour into the drying process, I started munching the tomatoes sprinkled with garlic, salt and pepper and could not resist it. It was only slightly wilted but because it was already tasting yummy. 
When my kid ran into the room he immediately said...give me the tomato sandwich..I dont remember talking about any sandwich for him that day but I took cue and immediately made this instant sandwich. You dont have to wait for days of sunlight for this yummy sandwich. It is instant and perfect snack for 4 PM. 
Most days this summer I have realized that what my kid has been asking or looking for is some  snack that is not dry. He tends to avoid eating food that is not warm to eat.
