A juicy herbed chicken breast on buttery toasted sourdough, with crisp lettuce, ripe tomato, and a swipe of garlicky lemon mayo. Pantry ingredients only — the kind of sandwich that earns its place at the lunch table by being made on a weeknight.
Pounding to even thickness is the single most important step. A whole chicken breast straight from the package is shaped like a wedge — the thin tip burns while the thick end is still raw. Five minutes with the side of a heavy pan fixes it.
If you have time, an extra hour in the marinade is never wasted. And if your tomato is watery, salt the slices and let them sit on a paper towel for a few minutes before building.
