Google “Low Sodium Christmas recipes” and you won’t find a lot, unfortunately. We know, we just tried it. But we have found some for you, so don’t lose hope. Ourcommuntiynow,com, for example, runs through where you can find low-salt ways to make turkey, gravy, mashed potatoes and cranberry sauce. It sounds a bit Thanksgiving, but I have made turkey for Christmas too, so it’s feasible.
Epicurious.com has a page of side-dish recipes that are low in sodium.
Good Housekeeping has a piece called 35 Healthy Christmas Recipes That Still Taste Totally Indulgent. It seems to start with sides too but does have an interesting salad take on the traditional Italian Christmas Eve feast of the seven fishes.
And while not Christmas focued, tasteofhome.com does have 40 Low-Sodium Recipes That Are Kind to Your Heart which has some interesting sounding main courses you could make for Christmas.
