Diana's meat counter has the *best* Italian sausages in Toronto proper.
I know that because I have tried them all - Commisso's, Cataldi, Gino's, M.Atlas, Galati Bros, Lady York, Fortino's, Pusateri's, the place up on Dufferin near Tim Horton's, the place further up on Dufferin just north of Costco, Highland, Furgiuele's, Zito's, St. Lawrence Market, plus Cumbrae, Healthy Butcher, Rowe Farms...
Diana Grocery makes real homemade Italian sausages. None of this frankfourcheeseitaliano stuff. No fennel overload. No unnecessary oregano. No phoney spice mixes. No hip and happenin' flavourings. Just real sausages like your nonno made them.
