This is what they call tarator in Bulgaria (tzatziki in Greece) and is absolutely wonderful and refreshing on a hot summer day: Shred a cucumber, salt it and cover with dill (the more the better for me), add crushed/minced garlic and olive oil. Add good Greek yoghurt, mix well and put in a fridge for a few hours. You can either drink it (in that case add some milk to achieve more fluid consistency), use as a dipping sauce with grilled meat or vegetables (typical tzatziki use) or eat on its own. Some Bulgarians also mix in crushed walnuts, which adds a nice slightly bitter aftertaste. The dill is extremely nice in this. Salmon (especially smoked) and dill are a natural fit. If you have new potatoes, just steam them and mix with dill and/or parsley with olive oil for a quick fragrant spring salad.
