Add processed cheese, mozzarella cheese, grated potato, green chillies, oregano, garlic paste, salt, black pepper, chopped corn, red capsicum and green capsicum to a mixing bowl.
Form small lemon sized balls (approx 2 tablespoons). Ensure they are tightly packed to prevent them from splitting open while frying. Place the balls on a plate lined with parchment and freeze for 20 minutes
Heat oil for frying in a kadai. The temperature of oil can be from 180C to 190C. Add the cheese balls one by one. Do not crowd the kadai, do multiple batches instead.
