Ingredients
  

For the beef
  • 1.5 pounds beef sirloin or flank steak, thinly sliced
  • 2 tablespoons cornstarch
  • 2 tablespoons vegetable oil for searing the beef
For the vegetables
  • 1 green bell pepper sliced
  • 1 red bell pepper sliced
  • 1 medium onion, sliced
  • 3 cloves garlic, minced
For the sauce
  • 1 can diced tomatoes (14.5 ounces), drained
  • 3/4 cup beef broth
  • 1/4 cup low sodium soy sauce
  • 1 tablespoon Worcestershire sauce
  • 1 teaspoon brown sugar
  • 1/2 teaspoon ground black pepper
  • 1/2 teaspoon paprika
  • 1/4 teaspoon red pepper flakes (optional) for added heat

Method
 

Preparation
  1. Place the sliced steak in a bowl and toss with the cornstarch until evenly coated.
  2. Heat the vegetable oil in a skillet over medium-high heat. Sear the beef for 2 to 3 minutes until lightly browned. Transfer the meat to the slow cooker.
  3. Add the sliced peppers, onion, and garlic on top of the beef.
  4. In a separate bowl, whisk together the diced tomatoes, beef broth, soy sauce, Worcestershire sauce, brown sugar, black pepper, paprika, and red pepper flakes.
  5. Pour the sauce mixture over the beef and vegetables in the crock pot.
Cooking
  1. Cover and cook on LOW for 6 to 7 hours or HIGH for 3 to 4 hours, until the beef is tender and the peppers are soft.
  2. Stir well before serving.

Notes

Serve hot over steamed rice, noodles, or mashed potatoes. Enhance flavor by marinating beef in soy sauce and garlic before cooking. Consider adding carrots or mushrooms for more heartiness.
