I'm going to try making my own version of Round Table's Polynesian Sauce this weekend. This is the recipe I found online for it, I'm hoping it works.
Round Table Pizza Polynesian Sauce for Maui Zaui Pizza
Juice of 4 oranges
Zest of one orange
2 cloves of garlic, grated
One tbs finely diced onion
2 tsp olive oil
Dash of salt
1/2 tsp ground ginger
4 tbs brown sugar
1/2 cup pineapple juice
1/4 cup Mai Ploy Sweet Chili Sauce (any brand would likely work fine)
Soften onions & garlic in olive oil with a dash of salt, then mix in all ingredients. Cook over medium to medium-low heat for 20-30 minutes, or until reduced & thickened. Spread on homemade pizza dough, top with whatever you like!
