I have prepared mixed dinners for vegetarians, vegans, and meat eaters. Not a problem for me, I used to eat meat and only gave that up about 8 years ago.
Since my cancer surgery where my gallbladder was removed it was a good thing I gave up meats. I feel you on the arthritis. I use a home remedy that seems to help. Gin soaked golden raisins. The fermented juniper from the gin interacts with the sulfur dioxide used to make the golden raisins. I scoop out 9-11 raisins a day, drain off the gin, and consume.
This helps with the arthritis pain that comes with Crohn's. It helps others as well, I heard about it from a friend and have been doing this for 2 years now.
one large box of golden raisins fits in a 1 quart canning jar, fill with gin. Gets to full strength in 5 days. I leave the leftover gin, add raisins, top off with gin for the next batch. Each lasts me about 2-2.5 months, very cost effective.
