Bacon, Lettuce, Avocado and Tomato Sandwiches (AKA the BLAT)

Pro tips

• Slice the avocado and tomato just before assembly to prevent browning and maintain texture.
• Pat the bacon dry with paper towels before layering to avoid excess moisture that will make the bread soggy.
• Choose ripe but firm heirloom tomatoes with minimal seeds for better sandwich structure and flavor.

Substitutions

• Green leaf lettuce → butter lettuce or romaine (milder or crunchier texture)
• Heirloom tomato → vine-ripened tomato (similar flavor profile)
• Semolina bread → sourdough or ciabatta (sturdy alternatives)

Storage & make-ahead

BLAT sandwiches are best eaten immediately. If you must prepare ahead, store components separately and assemble just before serving.

Can I make BLAT sandwiches ahead of time?

Not recommended. Assemble just before eating to keep the bread from becoming soggy and to preserve the crisp texture of the lettuce and bacon.

What bread works best for a BLAT?

Hearty, structurally sound bread like bakery semolina bread works well. Avoid soft white bread, which won't hold up to the moisture from tomato and avocado.

How do I prevent the avocado from turning brown?

Slice and assemble the sandwich immediately before serving. Keep the avocado pit nearby if storing; it slows oxidation slightly.

Can I use regular tomatoes instead of heirloom?

Yes, but heirloom tomatoes have better flavor and fewer seeds, making them ideal. Choose ripe, flavorful tomatoes for the best result.

What type of lettuce works best?

Green leaf lettuce adds a tender texture. Avoid iceberg, which is too crispy and bland. Any tender, mild lettuce works.
