Method
 

Preparation
  1. Slice 1.5 pounds of flank or sirloin steak into thin strips against the grain for tenderness.
  2. Heat 2 tablespoons of cooking oil in a hot skillet over medium-high heat, then sear the beef strips for about 3 to 4 minutes until browned.
  3. Slice the green, red, and yellow bell peppers and 1 large onion into even strips.
  4. In a separate bowl, combine 1 cup beef broth, 1/4 cup soy sauce, 3 minced cloves of garlic, and 1 teaspoon freshly ground black pepper.
Cooking
  1. Layer the browned beef, sliced bell peppers, and onion in the slow cooker.
  2. Pour the prepared sauce over the top, gently stirring to combine.
  3. Set the slow cooker to low heat and cook for 6 to 8 hours until the beef is tender.
  4. About 30 minutes before serving, mix 2 tablespoons of cornstarch with 2 tablespoons of cold water to create a slurry, then stir this mixture into the slow cooker.
  5. Cover and continue cooking until the sauce thickens to your desired consistency.

Notes

For a lighter version, use leaner cuts of beef or substitute chicken or turkey. Serve over rice or egg noodles, and consider using gluten-free soy sauce for a gluten-free option.
