1/4 cup fresh lime juice
1 teaspoon palm sugar (or regular sugar)
1 fresh red chili pepper, sliced
1/4 teaspoon salt (or to taste)
3 ripe mangoes , peeled and cut into 1/2-inch dice
1/4 cup fresh cilantro leaves , finely chopped
2 tablespoons shallots , fried (or French fried onion)
Prepare the dressing by combining the lime juice, palm sugar, chili, and salt in a small bowl. Stir to mix well and set aside.
Combine the mango and cilantro in a large bowl. Pour in the dressing and toss to mix well. If you plan to serve the dish later, you should transfer everything into a sealed container and store it in the fridge, up to 1 day.
Toss in the cashews and fried shallots. Mix well.
