In a blender or in a bowl using an immersion blender, combine yogurt, feta, mayonnaise, dill, 2 teaspoons lemon zest, 2 tablespoons lemon juice, garlic and oil. Blend until smooth. Refrigerate until ready to serve.
In a light-colored or stainless steel 12" skillet, melt butter over medium. When butter is foamy, cook another 3 to 5 minutes, until brown specks appear, swirling and stirring often.
To skillet, add radishes and season with salt and pepper. Stir radishes to coat in butter. Continue cooking 7 to 8 minutes, stirring occasionally, until radishes are tender.
Spread yogurt-feta sauce on platter and transfer radishes over top of sauce. Garnish with dill and more sauce, if desired.
