Mushrooms are my favorite here for their meaty bite and savory flavor. I still remember my kids picking out all the mushrooms one by one when they were young and now they always ask for extra.
Storage Tips
Leftovers keep well in a sealed container in the fridge for two to three days. When reheating use a skillet on medium heat and add a splash of water if the sauce thickens too much. Avoid microwaving for long or the vegetables may lose their crispness.
Ingredient Substitutions
If you do not have chicken breast try boneless chicken thighs for extra juiciness. You can swap oyster sauce for hoisin sauce if needed though you will get a sweeter flavor. If zucchini is not available broccoli florets or snow peas make great seasonal swaps.
Serving Suggestions
Serve this over a bed of jasmine rice or scoop it into lettuce cups for a low carb option. For added crunch top with toasted sesame seeds or thinly sliced scallions. A simple side of stir fried greens brings a restaurant meal home.

Quick Cultural Context
