Drizzle the steak with olive oil and season generously with salt and pepper. Let it sit while the grill heats. Grill for about 4–6 minutes on each side or until desired doneness.
Slice the zucchinis lengthwise, drizzle with olive oil, and season with salt and pepper. Grill for 3–4 minutes per side until tender.
Mix Greek yogurt, chopped fresh herbs, and lemon juice in a bowl. Adjust seasoning if needed.
Remove the steak from the grill, let it rest for 5–10 minutes, then slice against the grain.
Assemble the bowls with rice or quinoa, topped with grilled steak and zucchini, and drizzle with creamy herb sauce.
Notes
For a lighter sauce, use non-fat Greek yogurt. Allow steak to rest for juiciness and cut against the grain for tenderness.
