Prepare the meat and veggies:
Slice the steak into thin strips and cut the peppers and onions into even slices.
Mix the sauce:
In a bowl, whisk together soy sauce, brown sugar, cornstarch, beef broth, black pepper, and garlic until smooth.
Layer in the slow cooker:
Place the beef in the bottom of your Crock Pot, followed by the peppers, onions, and diced tomatoes. Pour the sauce mixture over the top.
Cook low and slow:
Cover and cook on Low for 6–7 hours or High for 3–4 hours, until the beef is tender and the sauce has thickened.
Serve and enjoy:
Spoon the pepper steak and sauce over rice or noodles. Garnish with green onions or sesame seeds if desired.
