Colorful bell peppers and juicy steak come together in an Asian-style sauce in this easy pepper steak stir-fry recipe. Serve over rice for a better-than-takeout weeknight dinner!
Cook the veggies. Heat 1 tablespoon canola oil over medium-high heat in a wok or skillet. Add the prepared onions and peppers to the hot oil and season with salt and pepper; cook for 5 to 6 minutes, or until tender. Stir in the garlic and continue to cook for 30 seconds, or until fragrant. Remove veggies from the skillet and set aside; keep covered.
Make the stir-fry sauce. In the meantime, prepare the sauce by mixing together soy sauce, rice vinegar, sesame oil, beef broth, sugar, ginger, and cornstarch.
Cook the steak. Add the rest of the canola oil to the skillet and raise the heat to high; add the steak, season with salt and pepper, and cook for 2 minutes per side.
Put it all together. Stir the vegetables back into the skillet and pour in the sauce; stir and continue to cook for 1 to 2 more minutes, or until heated through and the sauce has started to thicken.
Serve. Remove from heat, garnish with green onions, and serve over rice or cauliflower rice.
