Simple yogurt herb sauce
Whole milk yogurt
Lime or lemon juice?
Mix all that stuff together. Chop the herbs up well. No sense biting into a big chunk of green onion. Only pick a couple of the optional items so it doesn’t get too complex.
I used to try yogurt sauces and they never worked but recently they have been turning out really well. I think it’s because I didn’t used to add salt. Fresh herbs are also important, though I still use dill from a jar. I bet this would be better with fresh dill.
You could also add chopped cucumber.
Use this as a dip for veggies or in gyros, burritos or other sandwiches.
Add mustard and lemon juice for something that goes well with seafood.
