Ingredients

  • 1 1/2 pound beef steak - like flank steak sirloin, or chuck eye steak, cut into strips
  • 1 1/2 bell peppers cut into strips - We used 1/2 each of a red, green, and yellow pepper
  • 1/4 sweet onion cut into strips
  • 1/2 cup soy sauce
  • 1 tablespoon minced garlic
  • 3 tablespoons brown sugar
  • 2 tablespoons tomato paste
  • 2 tablespoons cornstarch
  • black pepper

Instructions

  • Preheat griddle on low.
  • While griddle is heating up, make the pepper steak sauce by combining soy sauce, minced garlic, brown sugar, and tomato paste in a small bowl. Mix well and set aside.
  • In a separate bowl, add about 2 tablespoons of cornstarch and 2 tablespoons of water to make a slurry. The slurry should be pretty runny yet still coat the back of a spoon. If needed, add more water or cornstarch. Mix the slurry well and set to the side.
  • Begin cooking sliced bell peppers and onions on one side of the griddle.
  • Season the cut steak with a moderate amount of black pepper.
  • Add the cut steak to the hottest side of the griddle, taking care to not crowd the meat. Give each steak piece its own spot on the griddle to be able to develop a nice sear. Allow the meat to cook for about 2 minutes untouched, then begin to toss it together.
  • Add the cooked peppers and onions to the steak on the griddle and stir to combine. Then pour the pepper steak sauce on top of the beef and vegetables. Stir to combine the sauce, steak, bell peppers, and onions.
  • Add the slurry to the pepper steak, about 1 tablespoon at a time. Stir to combine. You should notice the sauce start to thicken almost immediately. For a thicker sauce, add more of the slurry. To thin out the sauce if needed, add some water.
  • Cook the pepper steak an additional 2-3 minutes, while stirring occasionally. Then remove from the griddle.
  • Serve over cooked white rice or cauliflower rice.
