In a large bowl, combine the mixed greens, cherry tomatoes, cucumber, bell pepper, red onion, shredded carrots, and radishes.

In a small bowl, whisk together the olive oil, balsamic vinegar, Dijon mustard, salt, and pepper until well combined.

Drizzle the dressing over the salad and toss gently to combine.

Serve immediately or chill in the refrigerator for 15 minutes before serving for a refreshing taste.
