Instructions

Step 1: In a small bowl, combine 3 tbsp mayonnaise with 10 finely chopped fresh basil leaves, stirring until evenly mixed to create basil mayo.
Step 2: Lightly brush 1 tsp olive oil on one side of each of the 4 white sandwich bread slices to prevent sogginess.
Step 3: Spread about 1 tbsp of the basil mayo evenly on the oiled side of 2 bread slices.
Step 4: Layer the 2 medium sliced heirloom tomatoes (about 4-5 slices per sandwich) evenly over the basil mayo on each slice, then sprinkle 1/8 tsp salt and 1/8 tsp black pepper over the tomatoes.
Step 5: Top each sandwich with the remaining bread slices, oiled side down, and gently press to secure.
Step 6: Cut sandwiches diagonally and serve immediately for a fresh no-cook delight.
