Marinated and grilled Skirt Steak is placed atop a bed of lettuce, tomato, onion and green olives and drizzled with homemade avocado dressing.
Combine marinade ingredients in small bowl. Place beef steaks and marinade in food-safe plastic bag; turn steak to coat. Close bag securely and marinate in refrigerator 6 hours or as long as overnight.
Remove steaks from marinade; discard marinade. Place steaks on grid over medium, ash-covered coals. Grill, covered, 7 to 12 minutes (over medium heat on preheated gas grill, 8 to 12 minutes) for medium rare (145°F) to medium (160°F) doneness, turning occasionally.
Meanwhile place dressing ingredients in blender container. Cover; process until smooth. Cover and set aside.
Carve steaks diagonally across the grain into thin slices. Season with salt, as desired. Arrange salad greens on serving platter. Top with tomatoes, onion, olives and steak slices. Drizzle with half the dressing. Serve with remaining dressing, as desired.
