Add one frozen bag or fresh sliced peppers and onions into a skillet over medium-medium high heat with 1 tbsp of oil.
while those are cooking, use kitchen sheers to cut your thin sliced steaks in small strips.
Add frozen bag of green beans to the peppers and onions (I buy the steamables and microwave them while I'm cutting my steak so they cook faster).
Next, add your steak strips into the pan and cook for a few minutes. Do not overcook the steak. While that cooks open and drain your water chestnuts.
Last, add water chestnuts and one bottle of stirfry sauce to the pan and turn heat to low. Once the sauce is heated through, ENJOY!
I always serve mine over quinoa and Chris uses rice but you can eat this alone and it tastes just as good!
