Preheat oven to 200^oC. Line a baking tray with baking paper. Process rice crackers in a food processor till they become crumbs. Transfer to a bowl and combine parsley, sesame seeds, paprika, salt and black pepper. Stir well. Spray or drizzle chicken pieces with olive oil. Roll chicken pieces in the crumb mixture, pressing crumbs on with fingertips. Place crumbed chicken on the lined tray. Roast for 40-50 minutes until evenly browned.
