Although we sell small tubs of tzaziki in our deli department, you can make your own to serve alongside the phyllo rolls for dipping. To do so, combine 1/2 cup yogurt, 1/4 cup sour cream, 2 chopped garlic cloves, 1 Tbsp. chopped fresh dill along with salt, pepper and lemon juice to taste, in a bowl. Coarsely grate 1/2 of a medium-sized English cucumber and squeeze all the excess water out of it. Stir the cucumber into the yogurt mixture and your tzaziki is ready.
