Add yogurt, cucumber, garlic, herbs to a bowl and mix well.
Add half each of the lemon zest , lemon juice and olive oil.
Add salt and pepper, to taste. Although I would add at least 1/2 tsp of salt and 1/4 tsp of black pepper…freshly grated is even better.
Taste sauce, and add rest of lemon zest, juice and olive oil to your preferred taste, and mix. Also add extra salt and pepper if needed.
Set aside in a pretty bowl/dish and drizzle with some extra olive oil.
Get out the pita chips and dip away!
