Mary's Zucchini with Parmesan for Two

Heat oil in a large nonstick skillet over medium heat. Add zucchini and cook, stirring every 2 to 3 minutes, until tender and most of the slices are golden brown, 20 to 25 minutes. Reduce heat to medium-low, sprinkle with salt and pepper; stir to combine. Sprinkle with cheese, cover and cook until the cheese is melted, 1 to 2 minutes more. Serve warm.
