Ingredients

• 2 slices – Bread (white, sourdough, or brioche)
• 1 large – Heirloom tomato (any variety)
• 2 tbsp – Mayonnaise
• Pinch – Salt and pepper (to taste)

 

 

How to Make It

Step 1: Prep the Bread
Preheat a skillet over medium heat. Spread 1 tablespoon of mayonnaise on both sides of each bread slice.
Tip: Mayo creates 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.
Tip: 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 structure and juiciness. Season each slice with salt and pepper.
Tip: Salting enhances flavor and draws out the tomato’s natural juices.

Step 4: Assemble the Sandwich
Spread the remaining 1 tablespoon of mayo on the toasted bread. Layer on the tomato slices, then top with the second slice. Cut in half and serve immediately.
Tip: Enjoy fresh for the best flavor contrast.
