Preheat oven to 400°F; place 2 tortillas on a sheet pan, then brush lightly with oil + pinch of salt; bake 5-7 min until slightly crisp + puffed

Meanwhile, heat 1 tsp oil in skillet over high; add the beef to pan, break into large chunks + sear undisturbed 2 min; flip meat over, season with 1 tbsp taco seasoning + pinch of salt/pep, then break into small pieces; cook 2-3 min until fully cooked + no pinkness remains

Divide meat between tortillas, sprinkle on 1-2 tbsp cheese per flatbread, then return to oven 2-5 min to melt cheese (if desired)—enjoy!
