Preheat the oven to 400°F. Line a baking sheet with parchment paper or aluminum foil.
Place the bread slices side by side on the baking sheet (they can be touching, but not overlapping). Bake for 3 minutes, until the bread starts to firm up.
Cover each slice with an even amount of the mozzarella cheese. Sprinkle the cheese with a bit of salt. Bake for 4 to 7 minutes until the cheese is melted and starts to brown a bit in spots.
Meanwhile, combine the tomatoes, olive oil, basil, garlic, salt and pepper in a medium-sized bowl. When the toasts have finished cooking, let them sit for one minute, then spoon the tomato mixture on top of the bruschetta. Serve immediately.
Notes
I used basil which is the classic herb in tomato bruschetta, but you could also add in or substitute thyme or oregano and that would be delicious. Fresh herbs only please — save the dried for tomato sauce. Marjoram, similar in flavor to basil, would also be nice.
