Herbed-Yogurt Dressing:

1. Combine Ingredients: In a small bowl, combine all the dressing ingredients: yogurt, oil, lemon juice, garlic, oregano, dill, salt, and mint.
2. Whisk: Whisk the ingredients together until they are well combined and the dressing is smooth. If you want a super smooth dressing, you can use an immersion blender to blend the ingredients together.
3. Store: Store the dressing in the refrigerator until ready to use, up to 5 days. The flavors of the dressing will meld together and become even more delicious over time.

Mediterranean Steak Bowls:

1. Preheat Grill: Preheat your grill to high heat (about 450℉). A hot grill is essential for searing the steak and grilling the vegetables quickly. If you don’t have a grill, you can use a grill pan or a cast iron skillet on your stovetop.
2. Prepare Steak: Pat the flank steak dry with paper towels. This will help it to sear properly and develop a nice crust. Sprinkle both sides of the steak generously with salt and pepper. Don’t be afraid to season the steak well!
3. Prepare Vegetables: Thread the cherry tomatoes and quartered red onions onto skewers. Brushing the vegetables with oil before grilling helps to prevent them from sticking to the grill and adds flavor. Brush the skewers with oil and sprinkle with salt and pepper. You can also grill the vegetables without skewers if you prefer.
4. Grill Vegetables: Place the tomato and onion skewers on the hot grill. Grill them, turning occasionally, for 5-8 minutes, or until the onions are softened and the tomatoes start to blister. Keep a close eye on the vegetables to prevent them from burning. The tomatoes will release their juices as they grill, creating a delicious sauce.
5. Grill Steak: Place the flank steak on the hot grill. Grill it for 4-5 minutes, then flip and grill for an additional 4-5 minutes for medium-rare (6-7 minutes per side for medium), or until an instant-read thermometer reads 140℉ for medium-rare or 150℉ for medium. Using an instant-read thermometer is the best way to ensure that your steak is cooked to your desired doneness. Don’t overcrowd the grill, as this can lower the temperature and prevent the steak from searing properly.  
    
6. Rest Steak: Remove the steak from the grill and place it on a plate. Cover it loosely with another plate or foil and allow it to rest for 10 minutes before slicing. Resting the steak allows the juices to redistribute, resulting in a more tender and flavorful steak. This is a crucial step that you don’t want to skip!
7. Assemble Bowls: While the steak is resting, divide the chopped romaine lettuce between 4 plates or shallow bowls. Top the lettuce with the sliced steak, grilled vegetables, hummus, chopped cucumbers, olives, and feta cheese. Arrange the ingredients attractively in the bowls.
8. Dress and Garnish: Drizzle the bowls generously with the Herbed-Yogurt Dressing. Garnish with lemon wedges and/or torn fresh mint leaves, if desired. The lemon wedges add a bright, citrusy flavor, and the fresh mint adds a refreshing touch.
9. Serve: Serve the Mediterranean Steak Bowls immediately and enjoy!
