grilled chicken wings with horseradish mustard sauce

i made this the other night for the gals as part of our low-cal meal plan this week. the prep was easy and a single serving clocks in at about 270 calories (this recipe makes 4 servings). i'm not usually a fan of horseradish, but it gives the dish an extra layer of flavor that combines nicely with the cool creamy mayo. i served it with an easy breezy tomato mozzarella salad.

ingredients:
1 tablespoon plus 1 teaspoon horseradish dijon mustard, divided
1 tablespoon evoo
1 teaspoon chopped fresh rosemary
1 lb chicken whings
3  tablespoons light mayonnaise
2  tablespoons water
garlic powder
s&p

directions:
preheat grill pan over medium-high heat and spray with non-stick cooking spray. combine 1 teaspoon mustard, evoo, rosemary, garlic powder (to your taste) and s&p in a small bowl. brush evenly over chicken. grill chicken about 3-4 minutes per side until it's cooked through and has nice grill marks. while the chicken is cooking, combine remaining 1 tablespoon mustard, mayonnaise, s&p and water in a bowl. to serve, drizzle sauce over grilled chicken while its still hot. this is the perfect recipe for your next summer bbq.
