Preheat oven to 350.

Start with the Quick Savory Tart Shell Recipe recipe. Keep shell in refrigerator until you are ready to add filling.

Quickly sauté your chosen mixture of greens in olive oil or steam them so that they are tender but retain their color.

Mix eggs, egg whites and sour cream in a bowl until fully combined. Add remaining ingredients and stir several times.

Gently pour egg mixture over tart crust.

Bake for 35-40 minutes or until filling is puffy and golden. Allow to cool on the counter for 10 minutes before slicing and serving.

For extra flavor: Add one onion, thinly sliced and deeply caramelized with ½ a tablespoon each of butter and brown sugar to the egg mixture along with the greens. This would also get a boost from virtually any kind of cheese you have sitting in the fridge – feta, goat cheese or gruyere would all be great additions. If adding cheese, I recommend adding half into the egg mixture with the greens and sprinkling the rest over the top just before putting the tart into the oven.
