In a large bowl, combine the diced green mangoes, cherry tomatoes, and thinly sliced red onion.
In a small bowl, whisk together the lime juice, vegetable oil, and honey (if using). Season with salt and pepper to taste.
Pour the dressing over the mango and tomato mixture.
Toss gently to combine, making sure the vegetables are well-coated with the dressing.
Let the salad sit for about 15-20 minutes to allow the flavors to meld together.
Garnish with fresh cilantro or parsley before serving.
Enjoy your meal!
