Creating your delicious Grilled Steak Bowl with Sauce & Grilled Zucchini is simple. Follow these steps for an easy preparation process:

1. Marinate the Steak: In a bowl, combine soy sauce, Dijon mustard, honey, red wine vinegar, and minced garlic. Add the flank steak and let it marinade for at least 15 minutes for maximum flavor.
2. Prepare the Zucchini: While the steak marinates, slice the zucchinis into bite-sized pieces. Toss the slices in olive oil, and season with salt and pepper.
3. Preheat the Grill: Heat your grill or grill pan over medium-high heat.
4. Grill the Steak: Place the marinated flank steak on the grill. Cook for about 4-5 minutes per side for medium-rare, depending on the thickness. Adjust the time based on your preferred doneness.
5. Grill the Zucchini: In the last 5-7 minutes of the steak cooking, add the zucchini slices to the grill. Grill until tender and slightly charred, flipping halfway through.
6. Rest the Steak: Once grilled to your liking, remove the steak from the grill. Let it rest for 5 minutes to retain its juices.
7. Slice the Steak: After resting, slice the steak against the grain into thin strips for maximum tenderness.
8. Assemble the Bowl: In a bowl, place a base of grilled zucchini, top it with sliced steak, and drizzle with any remaining marinade sauce.
9. Garnish: Optionally, sprinkle with chopped green onions for an extra flavor boost.

By following these simple steps, you’ll end up with a bowl that not only looks enticing but tastes incredible as well.
