Caramelized Onion & Heirloom Tomato Crostata

with Feta Cheese & Arugula

Crostata is the Italian word for a rustic, free form pie or tart. References to these open-faced pies have been found in some of the first Italian cookbooks published in 1465. They can be filled with seasonal fruits or vegetables and can be sweet or savory. This healthier crust is made with equal parts whole wheat and all-purpose flour and olive oil instead of butter.
