Preheat the oven to 400 degrees F. Lay a piece of Glad® Press ‘n Seal flat on the counter. Roll a piece of puff pastry out over it, into a 12 X 12 inch square.
Pick up the puff pastry by the edges of the Glad® Press ‘n Seal. Flip and fit the pastry into an 8 X 8 inch baking dish, making sure the pastry comes up the sides. Peel off the Glad® Press ‘n Seal. Crimp the edges of the pastry if desired.
Crack the eggs into a large bowl. Add the half & half, and beat well. Mix in the Hidden Valley® Ranch Dip Mix and shredded cheese.
Pour the egg mixture into the prepared baking dish. Bake for 20-30 minutes, until the center doesn't jiggle when shaken. Cool for 5 minutes. Then cut and serve!
NOTE: To make the night before, prep the pastry crust and the egg mixture. Keep them separate and cover well with Glad® Press’n Seal. Refrigerate overnight. When ready to bake, unwrap the crust and egg mixture. Stir again and bake for 30 minutes.
