Start by heating the avocado oil in a large skillet over medium-high heat. You gotta wait till the oil’s shimmering before moving on.
Next, toss in that sliced sirloin steak. Let it cook until browned, which usually takes 5 to 7 minutes. You’ll notice a tasty crust forming that’s perfect.
Now stir in the sliced onions, bell peppers, and mushrooms. Cook until the vegetables get tender, about 5 to 7 minutes more. The kitchen smells just right by now.
Time for the flavor hit. Add Worcestershire sauce, Dijon mustard, light brown sugar, Italian seasoning, and smoked paprika. Stir it all up and cook for 2 to 3 minutes so everything comes together.
While that’s going, start your rice if you wanna serve with it. Get it simmering on the side or just follow your usual method.
Notes
Serve over rice, or other desired base, and enjoy! If meal prepping, it can be stored in airtight containers up to 3 days in the refrigerator.
