Wash and remove the stems and roots of the radishes. Cut the radish into a ¼" dice.
1 small bunch radish
Chiffonade the basil by stacking up about 5 of the basil leaves at a time, then gently rolling them into a tube shape. Using a sharp chef's knife, slice the roll of basil leaves crosswise into thin, even strips. Repeat until all the leaves are cut into thin strips.
15 - 20 fresh basil leaves
In a medium bowl, mix together the yogurt, crumbled feta, diced radish, basil, and the black pepper until everything is well combined.
1 cup plain Greek yogurt, ½ cup crumbled feta cheese, ½ tsp freshly cracked pepper
Spoon into a serving bowl and enjoy with crackers, fresh veggies, or warm pita bread.
