OK, finally got a chance to go to RD quickly and their "pork pizza topping" comes from Bonici. They also carry a "beef topping" as well. Comes in five pound cases, two 2.5 lb.bags per case, and my store will let you buy one bag at a time, which is PLENTY for a home-based gal like me. I think this is a pork/chicken blend but cannot say for sure. It suits me fine and is as close as I can get to what I grew up with, your milage may vary! Tried the Hormel and they were terrible in my opinion, expensive to boot....
Sorry it took me so long to get back to you. Pizza with my pork topping is on the menu tonight....can't wait!
Good luck, Luke and Bob, on your own personal sausage quest....I have been there!
