My favorite recipe evolved from the ranch-type recipes. The base is equal mayonnaise and plain goat yogurt or kefir (any yogurt/ kefir/ buttermilk would obviously work and I've also used blended up cashews and water in place of the fermented dairy) herbs and spices are really flexible - I never measure, and it always tastes super yummy.
Ratios are totally approximate. 2T dill, 1-2 T Parsley, 1T Chives 1/4-1/2 tsp lemon-pepper seasoning, additional salt to taste and if you feel like it - garlic powder, onion powder, and herbamare. We use that as dip and salad dressing (kefir makes a better dressing consistency and yogurt a better dip)
I also make a grain free bread with almond flour and eggs and chop it up into cubes, mix with melted coconut oil and seasonings and bake it into croutons. It adds protein without "feeling" like it. It is super easy, just takes a little time. You could do that with whatever bread you prefer to eat.
