A "Berneray Tortilla" is a variation on the classic Spanish Omelette, but made specifically with Berneray goose eggs.
Here it is:
There's peppers, onions, ham and other stuff in there. Very nice it was, but a bit more heavier and filling than a normal (hens egg-based) omelette. Served best with sliced and friend potatoes, and a light but very chilled white wine for balance.
