Heat the oil in a wok, add the pork strips and fry for 3 - 4 minutes or until lightly colored on all sides. Remove the pork and its juices to a bowl and set aside.
Add more oil to the wok if necessary and add in the onion and ginger. Stir fry for 2 - 3 minutes until soft. Stir in the orange juice, honey, peanut butter, soy sauce and chilli powder, bring to the boil and stir to combine.
Return the pork and its juices to the wok and mix well. If the sauce thickens too much, add enough water to thin down.
Once the pork is piping hot - serve immediately with rice.
