Cut some bread into half centimeter thick and 5 cm long slices of toasts.
Put a slice of fresh Pecorino Toscano DOP on each toast and put them on parchment paper. Heat the oven to 200°C. Once hot, bake the toasts for 5-10 minutes. They should be crunchy and the cheese might melt. Put the butter into a frying pan and use it to melt the anchovies. This sauce is to be poured on the toasts, which must be served hot.
