Start by rinsing the mixed salad greens under cold water.

Halve the cherry tomatoes and dice the cucumber.

Thinly slice the red onion.

In a large mixing bowl, combine the salad greens, cherry tomatoes, cucumber, and red onion. Toss them lightly.

In a separate bowl, whisk together the balsamic vinegar, olive oil, and honey if using.

Drizzle the dressing over the salad mixture and toss gently to coat.

Sprinkle crumbled feta cheese on top and season with salt and pepper.

Transfer the salad to a serving bowl and enjoy immediately.
