A week ago today, we had lettuce wraps at P.F. Chang's. Last night, I did a homemade version. The flavoring wasn't as strong as the restaurant version, but it was good! Basic ingredients: chopped chicken breast, chopped onion, shredded carrot, diced bell pepper, minced garlic - all sauteed until browned. Stir in water chestnuts and add oyster sauce and simmer. Serve with lettuce leaves, or, this was also good on a bed of jasmine rice. In the past, I've also spiffed up a peanut sauce as a side.
