The Recipe

• 1 red onion, chopped
• 1 tbsp vegetable oil
• Pinch of salt
• 1/2 cup of water
• 3 tbsp honey
• 1 tsp dark soy sauce
• 1 tbsp light soy sauce
• 2 tbsp yeast extract (such as Marmite or Vegemite)

Directions:

1. Combine the marinade ingredients together in a plastic bag. Add the chicken pieces and stir to coat. Set in the refrigerator for at least 1-2 hours.

2. Heat 1 tbsp of oil in a large frying pan. Lightly fry the onions with a pinch of salt for 15 minutes or until softened. Add the onions into a bowl, leaving any oil in the pan.

3. Turn the heat up on the pan and add a little more oil. Setting aside the remaining marinade, stir-fry the chicken pieces until lightly browned and cooked through. Remove the chicken from the pan.

4. Add 1/3 cup of water, marinade, honey, soy sauce, and fish sauce, bringing to boil. Simmer for 3-5 minutes or until the sauce has begun to reduce.

5. Add the chicken and onion and simmer until completely cooked through.
