1In a medium-sized bowl, combine the Greek yogurt, fresh dill, lemon juice, garlic powder, salt, and black pepper.
Stir the mixture well until all ingredients are thoroughly combined.
Taste the sauce and adjust seasoning if necessary, adding more salt or pepper to taste.
Cover the bowl and refrigerate the sauce for at least 30 minutes to allow the flavors to meld.
Serve the herbed garlic slider sauce chilled as a topping for sliders or as a dip.
