Notes
Slice Steak Thinly – Cutting against the grain ensures tenderness.
Use High Heat – Helps achieve a good sear without overcooking.
Don’t Overcook the Veggies – Keep peppers crisp for texture.
Thicken the Sauce – Simmer just until the sauce clings to everything.
Serve Immediately – Best enjoyed hot and fresh from the pan.
