Air-Fried Plantains with Avocado-Mango Relish

We like to think of plantains as the banana’s amazing big cousin; they’re not quite as sweet, but they make fantastic chips. Look for mostly brown ones with some yellow on the peel. We’re suggesting Ataulfo (or champagne) mangos, which are the smaller yellow ones. They are creamy and have less fibrous centers with a much smaller flat seed inside—which means more fruit, even though they are small!
