We will be having Greek style lamb casserole this year. We have different food each year at Christmas and haven’t gone turkey for years. Tbh none of the family like it and find it fairly tasteless and dry. I think Christmas should be what you enjoy. Before the 1960s few people are turkey anyway at Xmas and if it wasnt for MIL insisting on turkey in previous years we’d never have it. As it is, I put my foot down a few years back and now we just do whatever takes our fancy each year. AIBU to think people just have turkey because everyone else does and they feel they “have to”?
