And you thought stir fry couldn’t be keto! This version of a classic favorite cooks quickly and is great for using up small amounts of extra vegetables.
Heat a large frying pan over high heat and add the oil, then add the garlic, ginger, and red pepper flakes. Cook for about 30 seconds until fragrant.
Add the bell pepper and celery, and cook for a few seconds more, then add the beef, and napa cabbage.*
Add the soy sauce and vinegar and cook for another minute or two more. The beef should be heated through and the vegetables should be tender but still crisp.
Stir in the green onions and sesame oil and serve.
Notes
*If you are using vegetables that are already cooked, just add them at the very end to reheat them.
