Spinach and presunto quiche

For a lighter dinner the other day, I made a quiche to go with the watercress soup I had made.
I love how quiche can be made with so many different type of ingredients to give it a different feel. I made this one with spinach, cheese, and presunto. And I used heavy cream as oppose to half-half. I think it comes out much better with heavy cream.
I follow my mom's portuguese recipe, but here is something very similar to what I make, except I use real butter on the dough (not shortening) and don't use cayenne pepper nor onions.
My assistant ate it pretty well.
