Creating the tropical mango salsa cups is a straightforward process that requires minimal cooking, making it an ideal dish for both beginners and seasoned cooks. Follow these steps to achieve the perfect mango salsa cups:

1. Prepare the Mangoes:
   • Peel and dice the mangoes into small, bite-sized pieces. Ensure they are ripe for maximum sweetness.
2. Chop the Vegetables:
   • Finely chop the red onion, red bell pepper, green bell pepper, and jalapeño pepper. Keep the pieces small for a consistent texture.
3. Mix the Ingredients:
   • In a large mixing bowl, combine the diced mangoes, chopped vegetables, and fresh cilantro.
4. Add Lime Juice:
   • Pour the lime juice over the mixture. This will not only add a tangy flavor but also help preserve the vibrant colors of the ingredients.
5. Season to Taste:
   • Add salt and black pepper according to your preference. Mix well to ensure all ingredients are evenly coated.
6. Prepare the Lettuce Cups:
   • Wash and dry the lettuce leaves, ensuring they are large and firm enough to hold the salsa. Alternatively, prepare your choice of serving cups.
7. Assemble the Salsa Cups:
   • Spoon the mango salsa mixture into each lettuce cup or serving cup.
8. Optional Avocado Addition:
   • If using avocado, gently fold in the diced pieces just before serving to prevent browning.
9. Chill Before Serving:
   • For the best flavor, let the salsa cups chill in the refrigerator for at least 30 minutes before serving.
