Step 1 Finely chop 1/2 the onions. Thinly slice remaining onions. Set aside. Place mince, breadcrumbs, egg and finely chopped onion in a bowl. Season. Mix well. Roll 2 level teaspoons of mince mixture into balls.

Step 2 Heat 1/2 the oil in a large, deep frying pan over medium-high heat. Cook meatballs, in batches, turning, for 4 to 5 minutes or until browned all over. Drain on paper towel.

Step 3 Heat remaining oil in the same pan over medium heat. Add capsicum, garlic and sliced onion. Cook, stirring, for 2 to 3 minutes or until capsicum is softened. Add peanut butter, coconut milk, chilli sauce, kecap manis, fish sauce, juice and 1/3 cup water. Cook, stirring, for 2 to 3 minutes or until heated through.

Step 4 Return meatballs to pan. Bring to a simmer. Simmer, stirring occasionally, for 3 to 4 minutes or until meatballs are cooked through.
