Preheat oven to 35 degrees. Using 5 crescent rolls line the bottom and sides of a glass pie pan. Press and stretch to fill gaps. Fill lined pie pan with cheese cubes and ham. Beat together eggs and parmesan cheese, pour over ham and cheese cubes. Using the remaining 3 crescent rolls, make 4 strips and arrange a lattice work over filled pie pan and tuck ends under to seal. Bake at 35 for 45 minutes or until the center is set.
