Mistura doesn't alway come in rolls but also in big chunk.
Rolls are great to make sandwiches with a steak meat (called "bifana" or "prego") or ham & cheese (called "misto").
When it's just baked, of course, a splash of salted butter makes it tastes amazingly good too.
(bread with mixtured flour)
"Mistura" simply means "mix".
This roll of bread is made more than 2 different kinds of bread flour.
Sometimes it's a mixture of only whites but mostly with brown and white flour.
