Sweet, delicate crab folded into melted Swiss and Gruyère, layered with creamy ripe avocado and whisper‑thin red onion. Pressed between buttery toasted sourdough, it delivers a crisp golden crust that gives way to warm, ocean‑bright richness and cool, velvety avocado. Light, luxurious, and quietly decadent — a coastal comfort classic with a fresh, modern edge.
Spread bread slices with mayonnaise and sprinkle with white pepper. Layer 2 slices with crab, avocado, onion, and cheese. Set remaining bread slices on top and spread each with 1 tsp. butter.
Melt remaining 2 tsp. butter in a large nonstick frying pan over medium heat. Put sandwiches in pan, unbuttered side down, and cook, turning once, until golden brown and cheese is melted, about 6 minutes total.
