For Christmas, I make the same thing every year. My family loves it, I never get any complaints, and they really won't let me leave out or substitute any of my staples. Nobody has a problem with it, but me. My staples are spiral ham, roasted potatoes, this brussel casserole thing with breadcrumbs, sweet honey orange carrots, and crescent rolls. The dishes by themselves are fine, but everything is dry, sweet, salty, and hot. The cumulative effect kind of just dries my mouth out. I make a sauce for my ham to try to put some zest back into the meal, but I need more tips. As I said, they won't let me substitute a dish out, so is there anything I can add to the meal to switch it up? Can I "alter" them in any way to keep the same spirit of the dish, but less dry? More sauces? Drinks? Thanks in advance! 
In our family tradition there is always a kind of fruit in a main dinner. This can be as simple as a can of mixed tropical fruit, it can be prunes which have been soaking overnight or flash cooked, it can be cranberry in sauce out of a jar or self cooked. Adding a simple bowl of fruit will add a different and not dry mouthfeel. As indicated in a comment, some communities use pickles in this place. And in the English traditions there are some sauces which are often served with meat, like mint sauce with lamb, red current jam or horseradish with beef, chutney from apple and curents with pork. All of these can be served straight out of a jar or can, just tip in a bowl or arrange on a dish for pickles or bigger pieces of fruit, which can be done in advance, adding very little work when serving the dinner.
