I surfed and googled and experimented with sauces online, and YUK.
Yesterday I played in the kitchen a bit and YUM.
ok so here goes, yes it has sugar...but NO OIL!
2 tsp cornstarch
1/2 cu brown sugar
1 tsp dried mince garlic
1-2 tsp oyster sauce
Mix ingredients in sauce pan, stir continuously while bringing to a boil, take off heat when thickened...
the ingredients are sort of guessed, so you may play a bit yourself if you need to with thickening etc... when I make it again, I will pay more attention and make needed changes ..
pour over steamed rice, stir fried veggies, etc...
