1 1/2cupsradishes, very thinly sliced. You can use a mandoline slicer for this because it slices the radishes paper thin, but a sharp knife will work fine.
1/2cupgreen onion, trimmed and thinly chopped. Use the white and green parts.
fresh cracked black pepper, to taste
Instructions
Combine all the ingredients in a bowl and mix well. Reserve a little of the sliced green onion for a garnish.
Chill until ready to serve, sprinkle with extra green onion and black pepper. Serve with crackers, chips, bread, or vegetable crudité.
Notes
You can substitute unflavored yogurt for some for some of the sour cream and/or mayo in this recipe if you need to cut the fat.
