I had a number of kosher guests ... not strictly kosher as I did not have a kosher kitchen. But they did not eat pork or shellfish. I offered turkey sausage and turkey bacon ... I don’t know the details about processing or casing ... but it was kosher. I got it frozen in bulk from restaurant supply. The turkey bacon wasn’t as popular as the turkey sausage with my ‘eat anything’ guests. I switched to turkey sausage completely so I always had that. The turkey bacon might be too lean, it cooked up flat
