If you're using frozen or refrigerated rice cakes, blanch them in boiling water for 30 seconds to a minute until they are soft. Then drop them into some cold water to stop the cooking, rinse & drain.
Make 3 diagonal cuts into the sausages
Skewer 3 pieces each of the sausage and rice cakes in an alternating pattern, then brush with a little oil.
In a small sauce pan, add all the sauce ingredients and bring to a simmer until slightly thickened.
Grill or pan fry over medium heat until both sides are crispy and slightly charred.
Brush the sauce on both sides. You can remove the skewers from the grill before doing adding the sauce but I like to keep it grilling just a few seconds longer.
Garnish with crushed peanuts and chopped green onions.
