Double Yikes. Don't get nervous. Life is full of challenges. Here are some helpful hints. Don't spread these around or the chinese restaurants will fill up with all the diabetics eating out.
Sauces to avoid Sweet and sour, Duck, Plumm Oyster, Hoisin
Any dish with very thick sauce, it is likely thickened with cornstarch
Anything steamed must be good for you
Good soups, egg drop, wonton (skip the wrapper, eat the inside), hot and sour
Dishes with thin, spicy or savory sauces are usually free from sugar and cornstarch
Surprisingly water chestnuts are low carb, baby corns are not
Kung Pau chicken is pretty much a safe bet
Protein and veggies are your mantra, cabbage is free
Who can beat a whole fish?
Tofu and green beans are not carb free
And my final, I am the customer, I reserve the right to pick and choose any subsitutions.
