I couldn't find the Chinese vinegar, so I used a really great balsamic vinegar as the recipe suggested. I also used diced onion instead of bell pepper (bell pepper doesn't really pair with shrimp for Chinese food very well...not complimentary, but a good effort ;) ! ) I also added 1/4 tsp. additional of red pepper flakes. Served this over brown rice and it was fabulous! My Chinese food-loving husband thought it was better than any (American) Chinese food he has had - and MUCH healthier!! To "Anonymous" who didn't feel this recipe measured up to "authentic" Chinese food: Authentic Chinese food is higher in fat, sodium, and cholesterol...Eating Well is a site for healthier recipies, not necessarily authentic Chinese. May I suggest that if you don't have anything nice to say, don't say anything at all. Definately lighten up.
