This recipe is delicious warm or cold, but I prefer a little warm as the pasta is a little more malleable then. I found golden balsamic at my local Stop and Shop so I haven't tried the substitution so I don't know how it works.
I like to dice everything up really tiny so it doesn't overwhelm the little orzos. If the honey and balsamic vinegar don't mix well, I recommend putting it in the microwave for a few seconds to loosen it up a bit. I also only use about half an onion as I don't like it to be the dominant vegetable. Mix everything while the orzo is warm so it combines well.
Pair with chicken wings or burgers and corn on the con for a delicious summer meal!
