Cut the freshly baked bread in half lengthwise and toast under a broiler or in a toaster oven.
Cut the garlic clove in half and gently rub on the toasted surface of the bread. Drizzle on a small amount of extra virgin olive oil. Cut the tomato in half and rub it against the surface of the bread until it is coated but not soggy. Add room temperature slices of jamón (or anchovies) and serve.
(Alternatively you can use a previously prepared or jarred salsa tumaca, a blend of tomato, olive oil and garlic, and spoon it onto the bread before adding the ham or anchovies.)
