1In a large bowl, combine steak, oregano, red pepper flakes, 1 tablespoon olive oil, 1 tablespoon lemon juice, 2 1/2 teaspoons garlic, and 1 teaspoon salt.
2Cover and let the steak marinate at room temperature for at least 30 minutes or up to 2 hours, or refrigerate up to 4 hours.
3Meanwhile, in a small bowl, combine the remaining 1 tablespoon lemon juice and 1/2 teaspoon garlic; season with a large pinch of salt.
4Let the lemon juice and garlic mixture sit for about 20 minutes.
5Add tahini, honey, 3 tablespoons olive oil, and 3 tablespoons water to the dressing mixture.
6Vigorously whisk the dressing, adding more water as needed, until smooth and easily pourable; season with salt and black pepper.
7Set the dressing aside.
8In a medium skillet over medium-high heat, heat 1 tablespoon olive oil.
9Add orzo and cook, stirring, until golden, 3 to 5 minutes.
10Add broth and bring to a boil, then reduce heat to medium-low.
11Simmer the orzo, stirring occasionally and adding more broth 1/4 cup at a time if needed, until broth is absorbed and orzo is tender, 8 to 10 minutes; season with salt and black pepper.
12Cover the orzo to keep it warm.
13Prepare a grill for high heat; preheat for 5 minutes.
14Brush grates with neutral oil.
15Thread 8 skewers with steak, onion, bell pepper, and tomatoes, alternating with 3 to 4 steak cubes per skewer.
16Drizzle kebabs with the remaining 2 tablespoons olive oil; season with salt and black pepper.
17Grill skewers, turning occasionally, until vegetables are tender and meat is cooked to desired degree of doneness, 8 to 15 minutes total.
18Transfer kebabs to a plate.
19In a large bowl, toss cucumbers and spinach with half of the reserved dressing.
20Stir chives into the orzo mixture.
21Divide salad and orzo among bowls; top with kebabs.
22Drizzle the remaining dressing over the bowls.

Tips
If using wooden skewers, be sure to soak them in water for 15 to 30 minutes before cooking so that they don burn on the grill; metal skewers do not need to be soaked.
When making the dressing, don be alarmed if the tahini seizes and becomes grainy at first; just keep whisking and adding small splashes of water and you ll reach a creamy consistency in no time.
