YUM! Loved these! I also used some extra veggies I had in the fridge (asparagus, sqash and onion) and they all turned out great. I didn't have a double boiler so I made the sauce in a small saucepan and left out the egg (I was afraid it would scramble) and it was still very tasty, I like it much better than traditional sweet and sour sauce. I think I will make this sauce in the future for egg rolls and such as well. Overall these beans were a big sucess, everybody loved them! Thanks for the awesome recipe!
