Instructions
- Season the beef with olive oil, garlic powder, smoked paprika, salt, pepper, and Worcestershire sauce. Let marinate for 15 minutes.
- Heat butter and olive oil in a large skillet. Add the onions and cook over medium-low heat for 15–20 minutes until caramelized. Stir in the sliced bell peppers and cook for another 5 minutes.
- Increase the heat to high. Sear the steak strips for 2–3 minutes until browned but still juicy.
