In a small bowl, whisk together the olive oil, minced garlic, lemon juice, shallot, red wine vinegar, honey, Greek seasoning, and dried oregano until well combined. This vinaigrette is the flavor backbone of the entire bowl, so make sure everything is emulsified together. Set aside about 3 tablespoons of this dressing in a separate small container—you'll drizzle this over the finished bowls for brightness. I like to taste the dressing and add a pinch of salt to brighten all the flavors before using it.
Add the cooked chicken chunks to a bowl and pour the vinaigrette (minus the reserved portion from Step 1) over them, tossing gently to coat every piece. Let the chicken marinate at room temperature for 15-20 minutes while you prepare the other components, or refrigerate for up to 30 minutes if you prefer more flavor development. The acid in the vinaigrette will season the chicken while adding brightness and depth.
While the chicken marinates, prep all your fresh components: slice the cucumber into thin rounds, halve the cherry tomatoes, pit the kalamata olives if needed, chop the fresh parsley and mint, and have the crumbled feta cheese and pickled red onions ready. I find it's easiest to arrange these in small bowls or on a cutting board so assembly is quick and everything stays cold and fresh.
Divide the hummus evenly between serving bowls (2 cups total should fill 4 bowls generously), creating a smooth base by gently spreading it across the bottom. Top each bowl with the marinated chicken from Step 2, then arrange the prepped vegetables and feta cheese artfully around the chicken. This combination of creamy hummus, tender seasoned chicken, and fresh vegetables creates a balanced, satisfying meal.
Drizzle the reserved dressing from Step 1 over the top of each bowl, then garnish with the fresh parsley and mint. Serve immediately with tzatziki on the side and your choice of pita chips, pita bread, or naan for scooping. Each component stays fresh and distinct while the flavors come together beautifully with every bite.
