Start by marinating the chicken tenders in a mix of ½ tablespoon olive oil, 1 teaspoon kosher salt, ½ teaspoon black pepper, and some of the lemon juice. Let it soak for about 15 minutes until it glistens and absorbs the citrusy flavors, being careful not to leave it too long to avoid excess salt.
Heat your grill and cook the marinated chicken until it’s nicely charred and cooked through, which takes around 10 minutes. Keep a close watch to prevent overcooking.
While the chicken is grilling, boil water in a pot and cook the orzo for about 8 minutes until al dente. Stir occasionally; it should be tender but firm. Avoid overcooking to prevent mushiness.
Whisk together the remaining olive oil, lemon juice, lemon zest, Dijon mustard, honey, kosher salt, and black pepper until creamy.
In a large bowl, mix the cooked orzo, sliced cucumbers, cherry tomatoes, red onion, kalamata olives, and feta cubes. Pour the dressing over the top and gently toss everything to combine without breaking up the feta too much.
Top the salad with the grilled chicken and sprinkle with chopped fresh herbs. Serve with lemon wedges on the side for added freshness. For the best flavor, enjoy right away rather than letting it sit too long.
