Swordfish with Grilled Nectarines and Avocado Salsa
This is one of those dead simple dishes that is so good. Peter grilled swordfish, Nantucket-style (basically, drenched in mayo :). We also put a halved firm nectarine on the grill, which had been brushed with some olive oil.
When those were finished, I cut cup an avocado, the grilled nectarine, and mixed them both with the juice of half a lime. This would work equally well with peaches and plums.
