  7. Prick bottom of pastry crust with a fork, nestle the onions into the pie base and pour in the filling. Sprinkle mushrooms and the remaining cheese on top.
  8. Place the pie tin on a cookie sheet and bake for 25-30 minutes until golden brown.
  9. This delicious mushroom and onion tart can be served for breakfast, lunch or dinner. It’s great at brunch with a green salad.


  1. Wash the kale thoroughly in cold water and spin dry in a salad spinner. Remove most of the tough stalk from the kale, massaging the leaves with fresh squeezed lemon juice, salt and olive oil to soften it up a bit.
  2. Chop, the kale, and place in a serving bowl with the shaved carrot. Top with pepitas or other nuts along with pickled onions. Dress with tarragon mustard vinaigrette.
