To make 1 sandwich, take two pieces of toasted bread and spread about 2 tablespoons of basil mayo onto each piece.
4 tbsp prepared basil mayo, 2 slices sourdough bread
Place several thick slices of tomato on top of one slice of bread, then season the tomatoes with flaky sea salt, and cover with the other slice of bread.
Flaky sea salt, 0.5 heirloom tomatoes, sliced thick
Repeat with the second sandwich. Cut the sandwiches in half and enjoy!
