Preheat the oven to 275°F.
In a bowl, combine the tomatoes with the basil and a pinch of salt and let marinate until the bruschette are ready to be eaten.
Rub the bread slices with the garlic cloves and then brush them with olive oil.
Put the bread in a tray and bake it in the oven for 12-15 minutes. This will allow the oil to bring the garlic flavor and lightly toast the bread.
When the toasts start to look golden, turn off the heat and take the tray from the oven. Let the toasts cool down.
Just before serving, to avoid the toasts to get mushy, put the tomato and basil mix on top.
