Instructions

Caramelized Onions - In a heavy bottom dutch oven, over medium heat, add the oil and butter to melt and warm. Cut onions in half, lay flat side down and slice 1/4 in. half moon shaped slices. Cook the onions for 30 min. stirring often until softened, lightly browned and caramelized. Remove the onions to a paper towel lined plate and set aside to cool. Preheat oven to 425 degrees F. and position a rack in the upper-middle section of the oven. Filling: Meanwhile, core and slice the tomatoes into 1/4" rounds. Roll out the pie crust onto a sheet pan lined with parchment paper' In a small mixing bowl, combine the cheeses, mayo and herbs together until blended. Place the caramelized onions in the center of the crust leaving a 1-1/2 " border for folding at the end. Place the tomatoes on top of the onions in 2 circular rows, and top each tomato slice with a dollop of the cheese mixture. Fold the outer edges partially over the filling and make pleats in the crust to maintain a rounded shape and rustic finished look. Finally, crack egg in a small bowl and whisk with a splash of water, then brush the edges of the crust to ensure a brown colored crust. Bake at 425 F for 25 min. Let it cool on a wire rack about 30 min. before slicing and serving.
