In a small jar with a lid or medium bowl, add yogurt, dill, garlic powder, salt and pepper.
Shake the jar or stir with a fork. That's it.
Serve with veggies. Dip tastes best after standing for 10 minutes. Shake or stir again after.
Notes
Store: Refrigerate in an airtight container for up to 7 days.
Regular yogurt contains more whey than Greek. If you have time, strain it in a colander lined with linen towel over a bowl for about 1 hour. If not, dip will accumulate more whey on top with time - just stir before serving.
I used garlic powder for a subtle garlic flavor. You can use tiny grated garlic clove too.
Dried vs. fresh herbs: If you are making this ranch dressing mid-winter, dried dill weed would work. Obviously not as good as fresh but you will get desired flavour pretty close.
