Lettuce Wraps

1 pound chicken, cut in really small pieces
1/2 onion, also cut in really small pieces
5 garlic cloves
1/4 c chopped water chestnuts (I didn't have these but they would be tasty! I threw in a little chopped celery for a little crunch)
1/4 c chicken broth
2 Tbsp balsamic vinegar
1/2 tsp ground ginger
1/8 tsp ground allspice
16 romaine lettuce leaves

Cook everything together (except the lettuce leaves) in a frying pan. Serve in lettuce leaves (wrap it like a burrito in the leaf). The recipe says to also put plum sauce in there, but I don't know what that is and didn't love the sound of it. But, try it and let me know how it is. We also put a little brown rice in the leaves with the chicken to stretch the chicken a little farther. These were good and similar to PF Chang's lettuce wraps!
