Avocado-and-Onion Salad

Since people in Cuba don't usually have ready access to salad greens, Lourdes Castro says, many will start a meal with this simple avocado salad instead. Cubans tend to use Florida avocados, which are widely available in the Caribbean; they're larger and smoother than Hass avocados, stay bright green when ripe and have a mild, slightly sweet flavor.
