Makes 8 mini tartlets or 1 large tart. You'll find the Harissa recipe here
If you don't feel up to making your own pastry use store bought frozen pastry such as a Careme. If using a store bought Harissa you might need to adjust the quantity of Harissa used. Start with 2 tsp and adjust as necessary. Danish feta is a creamy style of feta, which I prefer, but feel free to use whichever feta you have on hand or prefer.
