The method

4 clear steps.

Make the sauce.

Whisk the tamari, rice vinegar, honey, sesame oil, cornstarch, and ⅓ cup water until smooth.

Sear the beef.

Heat 1 tablespoon avocado oil in a large skillet over high heat. Sear the beef in two batches for 60–90 seconds per side; transfer to a plate.

Cook the vegetables.

Add the remaining oil, broccoli, bell pepper, and 2 tablespoons water. Cover for 2 minutes, then uncover and cook until crisp-tender.

Glaze and serve.

Return the beef to the skillet. Stir the sauce again, pour it in, and toss for 1–2 minutes until glossy. Finish with scallions and serve over rice.

Make it work.

Small details that matter most with gluten-free cooking.

Slice across the grain

Shorter muscle fibers make each bite more tender.

Use certified tamari

Standard soy sauce usually contains wheat; verify the entire label.

Keep the pan hot

High heat gives the beef color before it overcooks.
