Finely grate/chop zucchini using a food processor. Add some salt to the grated zucchini and let it sit for 20-30 minutes. This way the zucchini will release all it's moisture.
After 20 minutes, squeeze the zucchini, remove all the water and place it in another bowl.
Now add chopped scallion (green onion), red onion, green chili and coriander leaves. Also add yellow corn, dried dill leaves and minced garlic.
Add salt, chaat masala and rice flour and mix everything together.
Take the mixture of a size of a lemon ball and make a patty out of it. Repeat till the mixture is finished. I was able to get 6 patties.
In a pan heat 2 tablespoons of oil on medium heat. Once the oil is hot place the patties on the pan.
Cook for 2 minutes or till it's light golden brown in color and then flip to cook the other side.
