Bake in a 500 degree preheated oven on a pizza stone for 6-8 minutes. They should puff up into pillows. If you have some that stay flat, keep them aside and i will show you what to do with them later.
For the tzatziki, you need yogurt. If you are using regular yogurt, strain the liquid out using cheese cloth and a strainer set over a bowl. It can take a couple hours for it to drain.
You can also use good Greek yogurt which is thick enough that it does not need to be drained. I had both on hand so I mixed them together.
Place the drained cucumbers in the bowl of your food processor along with about 5 tablespoons of fresh dill. Add 2 diced garlic cloves and some salt and pepper. Pulse until smooth.
Tomorrow I will show you the rest of the sandwich recipe.
