A creamy yogurt sauce with cucumber and garlic.
Grate the cucumber using a box grater and place it in a clean kitchen towel. Squeeze out excess moisture to prevent the sauce from becoming watery.
In a medium bowl, combine the Greek yogurt, grated cucumber, minced garlic, olive oil, lemon juice, and salt. Mix well until all ingredients are blended.
Chop the fresh dill or mint and fold it into the yogurt mixture. Adjust the seasoning with more salt if needed.
Cover the tzatziki and refrigerate for at least 30 minutes to allow the flavors to meld.
Serve chilled as a dip with pita bread or fresh vegetables, or as a sauce for grilled meats.
