Slow Cooker Pepper Steak

1. **Prep the Steak:** Generously coat the top sirloin steak with freshly ground black pepper, massaging it gently. Dice the steak into cubes or slice it into strips as per your preference.

2. **Combine Ingredients:** Place the steak, diced onions, and bell peppers in a 6-quart slow cooker.

3. **Make the Sauce:** In a separate bowl, whisk together 1 cup of beef broth, soy sauce, brown sugar, ground ginger, and garlic powder. Pour this mixture over the steak and vegetables in the slow cooker.

4. **Thicken the Sauce:** Mix the remaining 1/2 cup of beef broth with cornstarch until smooth, then add it to the slow cooker. Stir thoroughly to ensure everything is well mixed.

5. **Cook:** Seal the lid on the slow cooker and cook on low heat for 5 hours.

6. **Finish and Serve:** Taste the dish and adjust the seasonings if needed before serving. Enjoy your savory, tender pepper steak!
