I have never had a boco burger and dont know exactly what it is, but I am guessing that it is a non meat, low fat burger?
OK, we have Quorn. It is great. I love it. There is one point per burger, and I think one per sausage (check that stat). They taste juicy, and meaty too. I think they are made from something called 'micro protein' which sounds awful, but it is fine. I think it might be based on mushrooms. Anyway, you can buy Quorn Burgers, Quorn Sausages, Quorn Pieces (great for stir frys, curries etc), and Quorn Cutlets (I have not tried them). I think maybe you can get Quorn Mince (Groundmeat in American). You will find the Quorn either in the freezers (burgers and sasauges) or in the cold cabinets for the other stuff. I shop in Sainsburys and they certainly stock it, but I am pretty sure other supermarkets will have it too.
Hope this helps!
