1/4 cup buttermilk
1/4 cup reduced-calorie mayonnaise
1 tsp orange zest
2 Tbsp store-bought horseradish
1 medium scallion(s), chopped
1 pound raw lean flank steak, or skirt steak
1 tsp kosher salt
1/2 tsp black pepper
6 cup mixed greens
Recipe
Preheat broiler.
Whisk together buttermilk, mayonnaise, zest, horseradish and scallion. Allow to sit for 15 minutes while preparing and cooking steak.
Season steak with salt and pepper. Broil 4 inches from heat until desired degree of doneness, about 4 to 6 minutes per side. Allow to sit for 5 minutes before slicing thin against the grain.
Divide greens amongst 4 dinner platters. Top each with about 3 ounces of steak and drizzle each with about 2 1/2 tablespoons dressing.
