Marinated White Anchovies with Soft-Cooked Egg, Roasted Onions, Salsa Verde, and Frisée

Anchovies usually play a supporting role in a dish, typecast as the salty accent. But we just love them, so we challenged ourselves to craft a sandwich that actually features them. We knew that if we succeeded, we’d have a sandwich that could have a small but faithful following. And so it came to pass. We adapted an interesting Scandinavian preparation that paired anchovies with eggs—the richness of the eggs balances the tartness of the fish. We liked it. And, as it turns out, so does that small (but ever-growing) band of devotees we’d envisioned.
