If you're hoping for a P.F Chang's copycat at home, these substitutions will not give quite the same flavor, but they can be used in a pinch with delicious results. If you don’t have rice vinegar, mirin can be used instead, but I would also add a squeeze of lime juice for added acidity since mirin is sweeter. Hoisin can be substituted with teriyaki sauce or equal parts molasses and soy sauce. Swap the sweet chili sauce for 1 tablespoon of honey and ¼ teaspoon red pepper flakes.
