Ingredients

Sandwich Ingredients

  • 2 slices crusty bread (sourdough, ciabatta, or rustic country)
  • 1 garlic clove, halved
  • 2 tablespoons mayonnaise, plus more to taste
  • 1 large heirloom tomato, cut into ½-inch thick slices
  • Flaky sea salt, to taste
  • Freshly cracked black pepper, to taste

Instructions

  1. Toast the bread: Toast the two slices of crusty bread until golden and crisp. While the bread is still warm, rub the cut side of the garlic clove gently over one side of each slice to release the garlic oils, infusing the bread with a subtle garlic flavor. Let the bread cool to room temperature, about 5 minutes.
  2. Prepare the sandwich: Spread 2 tablespoons of mayonnaise evenly over the garlic-rubbed side of each slice of bread. This creamy layer complements the fresh tomato slices perfectly.
  3. Assemble the sandwich: Place the tomato slices on one slice of bread, mayonnaise side up. Season the tomatoes generously with flaky sea salt and freshly cracked black pepper to enhance their natural sweetness and flavor.
  4. Close and serve: Top the seasoned tomato layer with the second slice of bread, mayonnaise side down, to complete the sandwich.
  5. Cut and enjoy: Slice the sandwich in half for easier handling and serve immediately to enjoy the fresh, vibrant flavors.

Notes

  • Use ripe, high-quality heirloom tomatoes for the best flavor.
  • Choose crusty bread varieties like sourdough or ciabatta to provide a crunchy texture that holds up to the juicy tomatoes.
  • Adjust the amount of mayonnaise to your liking or substitute with a vegan spread to make the sandwich dairy-free.
  • For extra flavor, add fresh basil leaves or a drizzle of balsamic vinegar if desired.
  • Consume immediately to avoid soggy bread from the tomato juices.
