Heat a skillet over medium-high heat and add olive oil. Arrange steak strips in a single layer and cook undisturbed for 2–3 minutes per side until browned. Remove and tent with foil to rest.

Reduce heat to medium-low in the same skillet. Melt butter and deglaze the pan by scraping up browned bits. Add sliced bell peppers and onion, stirring occasionally, and cook until softened and starting to caramelize, about 6–8 minutes. Stir in smoked paprika and soy sauce if using, cook for an additional minute, then remove from heat.

Heat a clean non-stick skillet over medium-low heat. Place one tortilla in the skillet, sprinkle half with cheese, layer steak strips, then vegetables, and top with remaining cheese. Fold the tortilla over to enclose the filling and press gently.
