Layer the vegetables and seasoning

• Drizzle olive oil into the slow cooker.
• Add the sliced onion, green bell pepper and red bell pepper to the bottom.
• Add the garlic powder, onion powder, black pepper, paprika and salt, then mix.
• Add the Worcestershire sauce.

Add the steak and stock

• Place the shaved steak over the vegetables.
• Pour in the beef stock.

Cook on low

• Cover and cook on low, stirring once or twice if you can.
• Shaved steak cooks quickly, so avoid cooking it all day or it can become chewy.

Melt the provolone

• About 10 minutes before serving, lay the provolone over the steak mixture.
• Cover until melted, then gently stir everything together.

Serve over rice

• Spoon over hot white rice.
• Top with extra melted provolone if you want it extra cheesy.
