Begin by evenly slicing 1 medium tomato and 125 g fresh mozzarella.
Add 4 slices sourdough bread to the grill or toaster, and cook until evenly golden brown. If grilling, don't take your eyes off the grill — it works fast!
Layer two slices of mozzarella on the toasted bread, followed by two slices of tomato. Sprinkle with Smoked salt (to taste), then drizzle with 1 teaspoon olive oil and 1 teaspoon balsamic vinegar (split between the four slices). Top with a few sprigs fresh basil, either whole or torn. Eat immediately.
Notes
Don't cut the fresh basil — basil bruises easily, and it negatively affects the flavour. If you don't want to use the whole basil leaves, use your hands to tear it into small pieces.
