In a fine-mesh sieve or colander, mix the onion with ½ teaspoon salt. Set aside for 5 minutes, then rinse under cold water. Transfer to paper towels.

In a large skillet set over medium heat, melt the butter. Add the cashews and cook, shaking the pan often, until the cashews are golden-brown, 3 to 4 minutes. Stir in ½ teaspoon salt and turn out onto a large plate to cool.

In a salad bowl, whisk together the mango chutney, oil, remaining ½ teaspoon salt, the black pepper and the juice of ½ lime. Add the spinach, onions and cashews and toss to coat. Sprinkle the mangos over the salad, squeeze the remaining ½ lime over the top, gently toss and serve.
