A great use for times when you have extra hardboiled eggs around the house. I don’t move fast enough to call this a quick recipe but it’s quickly becoming a family favorite. You can work ahead to make it a quicker dinner by stopping after the sauté step, cooling it a little, then mixing in the cheese, and putting the filling in the fridge overnight, then mix in the raw egg, assemble the tart and pop it in the oven when you’re ready to eat.
