Directions

Step 1: Marinate the Steak

In a bowl, whisk together soy sauce, garlic, ginger, and a touch of brown sugar. Toss the thinly sliced steak in the marinade and let it sit for at least 15 minutes (or up to 2 hours for deeper flavor).

Step 2: Sear the Steak

Heat a large skillet or wok over medium-high heat with a splash of oil. Add the steak in batches, cooking for 1-2 minutes per side until browned but not overcooked. Remove the steak from the pan and set aside.

Step 3: Cook the Vegetables

In the same skillet, add a little more oil if needed. Toss in the bell peppers and onions, stir-frying for 3-5 minutes until they’re tender-crisp.

Step 4: Make the Sauce

Whisk a bit of cornstarch with water to create a slurry. Pour it into the skillet along with the leftover marinade, simmering until the sauce thickens.
