We got the idea for this fabulous app when we heard a commercial on the radio. Trader Joes was advertising puff pastries with caramelized onions and feta, which could be found in their frozen foods section.
Homemade would taste better, we reasoned. And they wouldn't be hard to pull together.
So here you have our version.
Here's what you need and how you do it
2 small onions, sliced thinly
Olive oil
1-2 Tablespoons balsalmic vinegar
Feta cheese (Or any kind of cheese)
1 box Pepperidge Farm Puff Pastry sheets (found in the frozen foods--desserts section of your grocery store)
Preheat oven to 400 F degrees.
Caramelize onions by sauteing in olive oil over low heat for 45 minutes to an hour, stirring occasionally. They should turn golden, but not dark brown or charred. After 45 minutes, stir in balsalmic vinegar and heat for another 5 to 10 minutes.
Lay out one puff pastry sheet on lightly floured surface. Cut into small squares, about 1 inch by 1 inch. In the center of each square, place a few of the caramelized onion slices and some crumbled feta. Cut second sheet of puff pastry into small squares and lay one over each little mound of onion and feta (creating a sandwich effect).
Bake for 15 to 17 minutes. Can brush tops with butter/margarine or an egg wash (one egg beaten with 1 Tablespoon water) for a more golden finish.
