This summertime stalwart seems so simple. But it's also particular.
Why This Recipe Works
To stay true to the classic Southern Tomato Sandwich, we turned to heirloom tomatoes, hearty white sandwich bread, and a good old mayonnaise. We first marinated the tomatoes in extra-virgin olive oil, red wine vinegar, and salt and then used some of the tangy marinade to liven up the mayonnaise. After spreading it on each slice of toast, we topped the zesty mayo with shingled tomato slices and black pepper.
