Variations:
We love stir-fry recipes like this one for how easy and adaptable they are. Once you have the sauce down, you can really add whatever you want. We like to use both red and green peppers, but you can swap in whatever colors you like best.

Throw in some thinly sliced onions, mushrooms, or even broccoli if you’re really missing it. Want to up the heat? Toss in a jalapeño if you like things spicy. Not a fan of beef? This stir-fry will also work great with chicken or tofu.
