1. Defrost puff pastry. On a lightly floured surface roll to a circle 12.5 in diameter. Fit into a 10 quiche pan or deep-dish pie pan. Roll the edges toward the center and press lightly against the rim.
2. Cut the cream cheese into 8 equal strips. Place the strips like spokes in the bottom of the crust.
3. Beat the eggs, cream, salt, pepper, mustard, and chilis. Mix in the cheese. Pour into the crust.
4. Put the quiche pan on a baking sheet and bake at 375 degrees for 1 hour and 15 minutes, until a knife inserted in the center comes out clean. Let cool for 5 minutes, cut and serve.
