I actually made this recipe with shrimp instead of beef and it was very good.
Simple, nutritious to make. My son really liked the crunchy veggies. I also added partially cooked noodles from Whole Foods & because of that, added 1/2 c water to soy/vinegar mix to keep everything moist. Found the ginger/zest amts. to be just right. Definitely will be doing this one again.
Fast and simple.. Go easy on the ginger and zest.
