2 C white whole wheat flour
3/4 C butter
pinch of pink Himalaya salt
1 T cold water
Preheat oven to 350. Place flour and salt into a mixing bowl. Rub in butter till the mixture resembles coarse breadcrumbs. Stir in water until the mixture forms a ball. Press the dough into a tart pan and bake for 20 minutes until golden brown.
Place diced ham, sauteed spinach and caramelized onions into the crust, top with beaten egg, sprinkle with shaved grana padana and bake till firm, about 30 minutes. Once cooled, remove from tart pan.
