Ham, mashed potatoes and fresh pineapple chunks is a nice dish.
Cut up the pineapple yourself.
That’s something the two of us eat for an easy meal. It doesn’t seem quite complete for a holiday christmas meal, though.

Bake it in the crock, of course! Go ahead, it’s oven safe. cite. The real question is how to do the breadcrumb topping. Two ways to do it. First, the recipe: AB’s mac and cheese, natch.
If your oven is going to be full right up until dinner, then bake the mac ‘n’ cheese inside the crock of your crock pot. When it’s done (crunchies included), put the crock in the outer pot and keep it on warm or low.
If you’ll have some oven space open at the last minute (like, when your ham is sitting before carving), mix up the mac-n-cheese and put it in the crock, but don’t do the breadcrumb step. Keep warm like before, and put the breadcrumb mixture on top of the mac-and-cheese 10 minutes before dinner and bake. Because it’s warm, it only needs a few minutes of baking to brown the crumbs.
The second method would be my first choice, because the crumbs may soften a bit sitting on top of the cheese all day, but either way will work.
Alton Brown’s Pineapple. We have also done this with a brown sugar/ginger glaze that really complements the ham.
LOL, I missed that completely in your OP. Sorry.
If you don’t mind my asking (and a hijack), what is it about them that you hate? I can imagine hating some scalloped potato recipes, but the recipe used in my family (which we will eat on Christmas Eve) is insanely delicious (and simple). I personally think the best way to mess up scalloped potatoes is to put too much stuff in them. Anyway, just curious.
Your ham preparation needs have been answered. You can thank me later. 
As for sides… mixed veggies, cinnamon apples, some casserole… those will work.

I love spiced apple rings with my ham, but it’s been recently revealed to me that of the 7 other people on Earth who seem to know what I’m referring to, they all hate spiced apple rings. 
oops sorry…you said spinach is a no-no. But…but…this recipe is sooo good.
Without wanting to harsh anyone’s scallopy mellow, let’s just say they’re visually offensive to me. Scalloped Potatoes Stock Photos | Our Top 10 Scalloped Potatoes Images | Fotosearch I dunno…I must have a bad memory buried deep in my psyche or something. But we all dislike them.
I love apples with pork. I’ll be doing an apple-something with this meal. All suggestions are welcome!
The 'shrooms look great. (check!)
Well, okay, guess. But I’m still confused. How does adding grated cheese between the layers before you bake the potatoes affect the visual appeal so significantly?
Cheese Grits go good with ham. Of course, if no one at your table has a drawl, they probably wouldn’t recognize the dish…
That’s ok, you could make Cheese Polenta instead. 
I’m not so fond of them either. It’s not just grated cheese for me, it’s the whole milky sauce thing. But I’m the first to admit I have weird food issues. I don’t like any kind of creamy sauces. I rarely eat potatoes but I’d take a plain old baked potato any day. I’m outnumbered in this meal by about 18-1 so I go with the flow.
Wrong.
(ok, depends on what you mean by crunchy)
Fresh green beans should be steamed until you can just get a fork through. Any more than that and you’re just losing flavor and vitamins.
and bacon is fine with canned green beans, but don’t spoil the fresh ones with it.
Sorry, but fresh green beans is one of my favorite vegetables and I hate seeing people ruin them.
They get kind of a curdled, slimy look to them that you just don’t get with an au gratin. Plus, they’re very beige. TOO beige.
French cut, with butter, pepper, and slivered almonds. And yes, they need to maintain a degree of crisposity. I don’t dig the “baby food soft” texture at all.
