Heat oven to 375°F (350°F for dark or nonstick cooking sheet)
Unroll the crescent rolls and cut them into rectangles. Press down the two triangles together so the edges disappear. Arrange them on the cooking sheet in a circle with crescent rolls overlapping.
Layer cheese and ham.
Then cover with the crescent roll pieces. Tuck each piece under the middle.
Bake for 18-25 minutes or until golden brown and cooked thoroughly.
