You can actually eat Baguette with Serrano ham at any time. You should not make too many of them for a tapas buffet; otherwise your guests will already be full.
Wash and halve the tomatoes.
Cut the baguette into slices and toast lightly with a toaster, the toast should not be brown.
Rub the tomato halves onto the toast slices, so that the flesh has rubbed into the toast.
Drizzle a little oil on the slices and top with the ham.
You can also rub half a clove of garlic onto the bread before you rub the tomato on the bread.
Preparation time: 20 minutes.
