In a cast iron pan, heat oil and place the mini idlis. Fry on low flame until both sides are golden and crisp. Set aside.
In the same pan, heat oil and add finely chopped garlic. Fry for a few seconds.
Add cubed onions and fry for a couple of minutes.
Add cubed capsicum and again fry for a couple of minutes.
Next add Kashmiri red chilli powder, salt, sugar and soy sauce. Cook for a minute.
Add tomato ketchup and green chilli sauce. Cook for another minute.
Now add the prepared idlis and toss them well until the sauce is all coated. Add a tablespoon of water if it is too dry. Cook for a couple of minutes and let the idlis absorb the sauces. Remove from heat.
