Method

1. Spicy tomato sauce: Heat the oil in a medium saucepan on medium. Add the onion, chilli and garlic. Stir to combine. Reduce heat to medium-low and cook, uncovered, stirring occasionally, for 7 minutes or until the onion softens. Add tomato and water. Increase heat to high and bring to the boil. Reduce heat to medium and simmer, uncovered, stirring occasionally, for 20 minutes or until sauce reduces and thickens. Stir in sugar. Remove pan from heat and set aside to cool slightly. Transfer sauce to a small bowl. Cover and put in the fridge for at least 2 hours, or until well chilled.

2. Chicken meatballs: Put chicken mince, breadcrumbs, egg yolk, garlic and basil in a medium bowl. Season with pepper and mix well. Shape tablespoonsful of mixture into balls to make 24 meatballs.

3. Spray a barbecue plate with cooking spray. Heat on medium. Add meatballs and use a flat spatula to flatten slightly. Cook, turning once, for 7-8 minutes or until cooked through.

4. Serve meatballs with half of the tomato sauce, reserving remainder for steak sandwiches. Accompany with toothpicks.
