Wipe 2 mushrooms with a damp paper towel, remove stems + scoop out gills; heat 1 tbsp oil in a skillet over high + cook mushrooms 2-3 min per side until browned + tender; add salt/pep + set aside

Heat lightly oiled skillet over med-high; cook burgers with salt/pep 3 min on one side, flip over, cook 2 more min, then add 1-2 tbsp cheese to each burger, cover pan + cook 1-2 min until cooked through, no pinkness remains + cheese has melted

Add mushrooms bottom-side up to plates, top with burgers + drizzle 1-2 tbsp sauce onto each—nice job!
