Cheddar Cauliflower Popcorn

1 head of cauliflower (large, cut into small florets)
1 tablespoon olive oil
1⁄4 teaspoon salt
1⁄8 teaspoon black pepper
1⁄3 cup finely shredded sharp cheddar cheese

Heat oven to 450°F. In large bowl, toss cauliflower, oil, salt and pepper until well mixed. Pour mixture into ungreased 15x10x1-inch pan.

Bake 18 to 22 minutes, tossing halfway through bake time, until light golden brown and crisp-tender. Sprinkle with cheese. Let stand about 1 minute or until cheese is melted.
