Christmas seems like a very easy meal to make paleo! I can't really think of anything I need to change in my family's meal, besides passing on the stuffing.
I work on an organic farm in the summer, so we get a beautiful heritage, free-range, organic turkey that I pick up on Christmas eve, so fresh it hasn't even cooled down in the fridge yet. I roast it hard and fast to get the skin wonderfully crisp and keep it juicy. I cut off the legs at the thigh bone, wrap them in parchment, and roast them alongside the bird to allow them to finish at the same time as the breast meat is done.
We like to do roasted root vegetables (salsify, rutabaga, parsnip, carrots, turnips) in butter with fresh thyme and a touch of honey stirred in at the end. I like roasted brussel sprouts with reduced balsamic vinegar and bacon bits. I usually make roasted garlic mashed potatoes, which I pipe onto a baking sheet and bake quickly in a hot oven, make crispy-edged little "wells" to hold my mom's fabulous pan gravy (she makes it from the turkey neck, giblets, and heart). The totally-non-paleo part: cranberry sauce, made fresh with ginger and hot peppers, so amazing but packs a ton of sugar. It's basically cran-jam, but my brother's favourite part of the dinner and recipe I made up years ago! may have to have a smidgen this year...
For breakfast/appies it's easy: appies are alwasy 5-7 lbs of spot prawns my boyfriend caught the year before. We boil them quick and serve them with garlic butter, amazing and a treat for house guests. Breakfast is cold smoked salmon (lox) from my boyfriend's dad, served with fresh lemon wedges and capers. Perfect breakfast, flavourful, filling, and decadent. Totally paleo!
