Ingredients
- ½ cup mayonnaise
- ½ cup sour cream
- 3 – 4 tablespoons finely shredded fresh horseradish
- ¼ cup milk
- 2 teaspoons sugar
- 2 cloves garlic, minced
- 2 ¼ teaspoons cracked black pepper
- ½ teaspoon salt
- 12 ounces boneless beef sirloin steak
- 1 cup grape tomatoes
- 1 red onion, cut into 1-inch-thick wedges
- 1 tablespoon olive oil
- 1 5 ounce spring mixed greens
Preparation
Step 1
In a small bowl whisk together the first six ingredients (through garlic), 2 tsp. of the pepper, and 1/4 tsp. of the salt. Chill until needed.
Season steak with the remaining 1/4 tsp. pepper and 1/4 tsp. salt. Thread onion and tomatoes on separate skewers,* leaving 1/4 inch between pieces. Brush onion and tomatoes with oil. Grill the steak, covered, over medium heat 14 to 18 minutes or until desired doneness, turning once. Grill onion skewers 12 minutes, turning once. Add tomato skewers the last 1 minute of grilling; turn once.
Let steak stand 5 minutes. Slice into bite-size strips. Coarsely chop the onion.
Line serving plates with greens. Arrange steak, onions, and tomatoes over greens. Drizzle with 1/2 cup of the dressing. Sprinkle with additional finely shredded fresh horseradish. Pass remaining dressing or cover and chill up to 1 week.
