Step 1

Combine avocado, buttermilk, yogurt, parsley, chives, lemon juice and 1/8 teaspoon salt in a blender. Blend on high until smooth. Pour into a large bowl and add cabbage, snow peas, carrots and radishes; toss to coat.

Step 2

Heat oil in a large cast-iron skillet over medium-high heat. Pat scallops dry and cook until browned, 1 to 2 minutes per side. Top the slaw with the scallops and sprinkle with pepper and the remaining 1/8 teaspoon salt.
