Heat 1 tsp oil in skillet over high; add beef to pan; break into large chunks + sear undisturbed 2 min; flip meat over; season generously with salt/pep + fave spices; then break into small pieces; cook 2-3 min until fully cooked + no pink remains

Remove pan from heat + stir ¼-½ cup sauce into beef to warm through

Divide beef between bottom halves of two buns; top with 1-2 tbsp cheese + second bun half

Heat a clean; lightly oiled skillet over medium; toast sandwiches 2-3 min per side until warm + melty; looks good!
