  • 1 lb boneless sirloin steak, trimmed of fat
  • 1 tbsp plus 1/2 tsp Worcestershire sauce, divided
  • 2 zucchini, trimmed and halved lengthwise
  • 1/2 cup reduced-fat sour cream
  • 1 1/2 tbsp grated fresh horseradish

Pantry staples

  • 1 tbsp safflower oil, plus additional as needed
  • 1/2 tsp fresh ground black pepper
  • 1/2 tsp plus 1/8 tsp sea salt, divided


  1. To a large resealable bag, add steak and 1 tbsp Worcestershire sauce. Seal bag and refrigerate for 30 minutes to 24 hours, turning occasionally.
  2. Heat an outdoor grill or grill pan to medium-high and lightly brush grate or pan with oil. Remove steak from bag and season with pepper and 1/4 tsp salt; discard marinade. Brush both sides of zucchini with 1 tbsp safflower oil and sprinkle with 1/4 tsp salt. Transfer steak and zucchini to grill and cook for 4 minutes per side, or to desired doneness of steak. Transfer steak to a cutting board. Continue cooking zucchini for 4 minutes more, turning occasionally, until just tender.
