In a small bowl, whisk together the lime juice, Italian dressing, orange juice, minced garlic, sea salt, and black pepper until well blended.
In a separate mixing bowl, combine the cubed apple, mango, diced red bell pepper, onion, and chopped cilantro.
Pour the citrus-garlic dressing over the fruit and vegetable mixture. Gently toss until all the ingredients are evenly coated.
Serve immediately with tortilla chips, or pair it with grilled chicken or fish for a bright, fruity finish.
