Begin by selecting ripe avocados and mangoes, which should yield slightly to gentle pressure. Carefully slice the avocados in half, remove the pits, and scoop out the flesh with a spoon. Dice the avocados and mangoes into small, bite-sized cubes. Place them in a mixing bowl, ensuring you have a colorful base for your salad.

In a separate small bowl, add the fresh lime juice, minced garlic, chopped cilantro, chili flakes, and salt. Using a whisk or a fork, blend these ingredients together until they are well combined.

Pour the freshly made dressing over the diced avocados and mangoes in the mixing bowl. Use a spatula to toss the salad gently, ensuring that the dressing coats each piece evenly without mashing the avocados.

For the best freshness, serve the salad immediately on a colorful platter or individual bowls. If preparing in advance, store the avocado and mango separately from the dressing to avoid browning.
