Combine olive oil, minced garlic, lemon juice, dried oregano, thyme, salt, and black pepper in a mixing bowl to create a flavorful marinade.

Place the sirloin steak in a resealable plastic bag, pour the marinade over it, ensuring it’s well coated, and marinate in the refrigerator.

Prepare the tzatziki sauce by combining Greek yogurt, finely diced cucumber, minced garlic, chopped dill, and lemon juice in a separate bowl.

In another small bowl, whisk together olive oil, lemon juice, honey, minced garlic, and oregano for the lemon vinaigrette.

Heat a skillet over medium-high heat, sear the marinated steak for 4-5 minutes on each side, then let it rest.

Slice the steak thinly against the grain and assemble your bowl with cooked grains, sliced steak, cherry tomatoes, cucumber, red onion, and toppings.

Drizzle the tzatziki sauce and lemon vinaigrette over the bowl, and garnish with fresh herbs before serving.
