Dry roast the oats on low flame for a few minutes until they are slightly golden. Let it cool completely
Boil the potatoes and grate them (you may mash them as well, but I prefer to grate them as it gives a uniform texture)
In a large bowl, combine all the ingredients except oil. Bring the mixture together to form a soft dough
Heat oil in a frying pan
Pinch out a small portion of the mixture and make a ball. Gently flatten it with your palms making sure there are no cracks at the ends
Repeat with rest of the mixture
Place on hot oil and shallow fry on medium flame for 2-3 minutes
Carefully flip the cutlet and fry on the other side
Drain on a kitchen towel
Serve hot with mint chutney or dip of your choice
