-
1 large heirloom tomato (any variety)
-
2 tablespoons mayonnaise, divided
-
Salt and black pepper, to taste
Instructions
Step 1: Prep the Bread
Preheat a skillet over medium heat.
Spread 1 tablespoon of mayonnaise on both sides of each bread slice. Mayo helps create a golden, flavorful crust thanks to its oil and egg content.
Step 2: Toast the Bread
Place the bread in the skillet and toast for about 2 minutes per side, until golden and crisp. Remove and set aside. Keep the heat at medium to avoid burning and ensure even browning.
Step 3: Slice the Tomato
Cut the heirloom tomato into thick slices for maximum juiciness and structure. Season each slice with a pinch of salt and pepper. Salting enhances flavor and draws out the tomato’s natural juices.
Step 4: Assemble the Sandwich
Spread the remaining 1 tablespoon of mayonnaise on the toasted bread.
Layer the seasoned tomato slices generously on one slice.
Top with the second slice of bread, slice in half, and serve immediately.
