When saluting this meal, fly the maple leaf, not the Union Jack: this dish hails from Canada, not the sceptred isle with Big Ben and the Queen. Still, you'll feel like a queen (or king) with this tender steak, marinated in a sauce of parsley, Worcestershire, honey, garlic, and vinegar, then grilled to perfection. Served with zucchini rounds and sweet potato steak fries, you'll be humming "London Calling" to yourself as you savor that last bite.
Peel (if desired) and cut sweet potato into ½" thick fries. Trim zucchini ends, quarter lengthwise, and slice into ⅓" rounds. Stem and mince parsley. Mince garlic. Rinse steaks, pat dry, and season both sides with ¼ tsp. salt and ¼ tsp. pepper. On a separate cutting board, use a fork to pierce steaks 10-12 times per side. This will tenderize the meat and allow marinade to penetrate.
Cook the Sweet Potatoes
Place sweet potatoes on prepared baking sheet and toss with 1 Tbsp. olive oil and ¼ tsp. salt. Spread into a single layer and roast 15-18 minutes. Remove from oven, flip potatoes, and roast until browned and tender, 5-10 minutes. While potatoes roast, marinate steaks.
Marinate the Steaks
Combine parsley (reserve a bit for garnish), vinegar, Worcestershire, honey, garlic, 1 Tbsp. olive oil, 2 Tbsp. water, ¼ tsp. salt, and ¼ tsp. pepper in a medium mixing bowl. Measure out 2 Tbsp. marinade into a small bowl and reserve for finishing steaks. Place steaks in bowl with remaining marinade and turn to coat completely. Let marinate at least 5 minutes.
Cook the Steaks
Warm an outdoor grill or grill pan to medium-high heat and lightly coat grill with cooking spray. Lift steaks from marinade, allowing excess to drip off. Place steaks on grill and cook until charred and steaks reach a minimum internal temperature of 145 degrees, 4-5 minutes per side. Remove to a cutting board and rest 5 minutes before cutting into thin slices across the grain. Wipe or brush grill clean and return to medium-high heat.
Cook the Zucchini
In another medium mixing bowl, toss zucchini with 2 tsp. olive oil and ¼ tsp. salt. Lightly coat grill with cooking spray and place zucchini on grill. Cook, flipping occasionally, until charred and crisp-tender, 4-6 minutes.
Plate the Dish
Arrange sliced steak, sweet potato fries, and zucchini on a plate. Drizzle steak with reserved marinade and garnish vegetables with reserved parsley.
