Caramelized Onion Pesto Pie - cooking recipe

Ingredients

3 lbs sweet onions, thinly sliced
2 tablespoons olive oil
1 teaspoon sugar
1 teaspoon salt
1 pie shell (I've also used a Boboli Crust, puff pastry and phyllo dough with good results)
1/2 cup prepared pesto sauce
1/4 cup Dijon mustard

Preparation

Cook the sliced onion in the olive oil in a large skillet over medium heat, stirring occasionally, until the onions are soft.
Add the sugar and salt and continue cooking and stirring until onions are golden and caramelized, about 35 minutes.
Spread mustard on the crust of your choice.
Spread pesto over the mustard.
Spoon the onions into the crust and smooth to make an even layer.
Bake at 350 degrees for 20 minutes or until crust is light brown and cooked.
Time and temperature might vary depending on what type of crust you choose.
