Savory leek tart.
What a simple treat, and a simple recipe.
The most difficult part is making sure your leeks are clean. Chop and rinse to get rid of any grit. Quality pre-made pastry is a game changer, but if you love to make dough, you got this. 
Sauté a little, roll out the dough, spread your ricotta, add the leeks, herbs and Parmigiano. Bake it , enjoy yourself or take it to anyone. They will love it.
