Take one uthappam on a plate. Apply some olive oil and spread well. Add some green chutney and spread well too.Now arrange the veggies and sprinkle chaat masala powder. Close with another uthappam.
Grill this dosa sandwich in a preheated sandwich maker as per instructions. Serve dosa sandwich hot.
Notes
1. You can use any filling of your choice. 2. Do not make thin dosas, it will be difficult to grill.
