Preheat the grill to medium-high heat.

In a bowl, mix olive oil, garlic powder, paprika, salt, and pepper. Coat the chicken breasts with the mixture.

Grill the chicken for about 6-7 minutes on each side or until fully cooked.

Remove from grill and let rest for 5 minutes before slicing.

In a large mixing bowl, combine mixed greens, cherry tomatoes, cucumber, red onion, and feta cheese.

Slice the grilled chicken and add it to the salad.

In a small bowl, whisk together olive oil, balsamic vinegar, honey, Dijon mustard, salt, and pepper.

Drizzle the vinaigrette over the salad and toss to combine.
