Marinate the Steak: Combine olive oil, minced garlic, lemon juice, dried oregano, thyme, salt, and black pepper in a bowl. Coat the steak and let marinate for 30 minutes to 4 hours.

Prepare the Tzatziki: Combine Greek yogurt, grated cucumber, minced garlic, lemon juice, and salt in a bowl. Stir until well combined and refrigerate for 15 minutes.

Make the Vinaigrette: Whisk together olive oil, lemon juice, minced garlic, dried oregano, honey (if using), salt, and black pepper in a bowl until smooth.

Cook the Steak: Heat a skillet over medium-high heat. Sear the steak for 4-5 minutes on each side until medium-rare. Let rest for 5 minutes before slicing.

Assemble the Bowl: Start with cooked grains, layer with sliced steak, fresh veggies, roasted chickpeas, then drizzle tzatziki and vinaigrette over the top.
