equal parts mayo, sour cream (or plain yogurt), and milk (about 1 C. each, but I eyeball it)
1 fresh garlic clove, pressed or finely minced (or substitute garlic powder)
1 t. salt
2 t. dill (very important, do not omit)
1 t. onion powder
a squeeze of fresh lemon juice
generous sprinkling of dried parsley, Italian seasoning, and black pepper
Whisk together and use as dip or salad dressing. Flavor improves and consistency thickens after refrigeration, but you can serve it immediately too.
