Jennie, I usually fix close to the same thing every year too. I did decide last year to switch regular mashed potatoes out with mashed sweet potatoes. Those go better with mac and cheese anyway, not so many carbs. Made them the same way as regular with adding a little milk and pepper and butter.
I may try a frozen cranberry marshmallow salad this year as something new. Also want to do some type of different pumpkin dessert recipe (something besides pie). Not too worried because whatever it is, it will be gone in 10 minutes.
