If you like the flavour of polenta this is a good alternative to the more traditional pizza base. The mixture is quite loose and the addition of yogurt and egg gives it a more scone-like texture
Why not make these as a change from a traditional sausage roll. I often make these using vegetarian burgers as well as with a meat burger. They are full of flavour with a coarse texture. These are a great way of having a burger without the bap. You can also use meatballs.
