I know everyone has a recipe for this. However, in this recipe you avoid the sauce becoming runny and also don't have to deal with cucumber seeds.
1 large cucumber
Fage fat free yogurt
flavorful olive oil
fresh dill, leaves removed from several stalks
garlic, finely chopped
freshly ground pepper
Skin cucumber and slice in half lengthwise. Scoop out seed with a spoon. Thinly slice cucumber and place in a bowl. Sprinkle salt over cucumber slices and let sit for 20 minutes.
Place chopped garlic and dill in another bowl. Cover with olive oil and then squeeze juice from one lemon. Add fresh pepper.
Drain accumulated water from cucumbers. Stir yogurt into lemon/olive oil mixture, then stir in drained cucumbers.
Voila. This is great served with grilled chicken breast, salad with lemon juice dressing and hot chickpeas. A great way to make the chickpeas is to saute garlic, onions and colorful bell peppers in olive oil, and add a can of chickpeas. (If you have the time, it always tastes better to make your own beans from scratch.)
