A great stir fry is all about high heat and fast cooking. The beef gets a quick sear while the peppers stay crisp-tender, and a simple sauce ties everything together in minutes.
This is the weeknight dinner you will come back to again and again. Prep everything before you start cooking, because once the wok is hot, things move fast.

- Keeps vegetables and proteins from steaming
- Makes quick sauce reduction easier
A flat-bottom wok is the most useful upgrade if you cook stir-fries more than once in a while.
