Chop fresh spinach and place in microwave safe bowl. Sprinkle lightly with about 1 Tbsp of water. Cover with plastic wrap and microwave for 1-2 minutes to wilt. Drain and squeeze out excess juice; set aside.
Place puff pastry on a work area lightly dusted with flour; roll out slightly larger than the original sheet. Cut each sheet into 3 pieces.
Press one piece into the bottom and sides of an individual quiche pans or a 4-5 inch custard cup. You will need 6 pans or cups.
Cut off excess dough; discard excess pastry or use to "patch" uneven/thin places in lined pans. Place prepared pans on a baking sheet.
Place 1 Tbsp or 1 strip of crumbles bacon in each pastry lined pan. Divide spinach, cheeses, onions, and tomato evenly among pans.
In a bowl, whisk together half n half, sour cream, eggs, salt and pepper. Evenly pour into all pans.
Bake at 350 degrees for 40-50 minutes or until set in middle. Makes 6 individual quiche but you can cut in half and serve up to 12. HOwever, I can easily eat 1 by myself!
