Christmas dinner/snack ideas I can make in advance?

on the cookies question (in addition to whatever you already like & make), three relatively unusual ones: pferrenusse spicy cookies http://allrecipes.com/recipe/pfeffernusse-cookies/
kipfel (Eastern European cookies with sour cream dough, filled with nuts +/or jam) http://easteuropeanfood.about.com/od/crossculturaldesserts/r/roszke.htm and a chocolate entry, Nanaimo bars http://allrecipes.com/recipe/nanaimo-bars-iii/

Can someone tell me ideas for what types of cookies (besides shortbread) I could do? Any recipes for rolls that you know are delicious? I seem to get lost googling and never get anywhere . Any tried and true ideas out there? I appreciate the suggestions and the snack ideas. I think half our day will be sort of traditional Christmas food (rolls, yams, stuffing, roasted vegetables) and then half at least will be anything to keep kids fed and out of the kitchen. I love the roasted chickpeas idea, and I think veggies and dip would work well too. We will have to feed the 6 of us first thing Christmas morning and hope to make my favourite cinnamon bun recipe (bread maker) but haven't tried to freeze them yet so unsure if I bake first or just rise and freeze.

Can traditional Christmas dinner items be prepped and frozen, or just done ahead of time? Perhaps the day before?

I do a very simple pan of chicken enchiladas that I assemble a day or two before and bake when ready. When I serve, I do a taco bar kind of buffet, diced tomatoes, shredded lettuce, avocado, salsa, sour cream, and tortilla chips.

any cookies would do really well frozen, just mix up the dough and freeze, and bake up till the day before or even before that and store in an airtight container. Shortbread is a favourite during christmas times and could be decorated and flavoured in so many different ways, sweet or savoury are both amazing. Most baked cakes also defrost beautifully!

you can freeze buns, cookies, rolls (baked or unbaked), then quickly bake or defrost. make a lasagna or simplhy sauced other pasta casserole for one side dish and/or kid meals. for snacks and energy, nuts (raw or roasted) and dried fruit, also roasted garbanzos (chick peas) with simple salt-pepper or more ambitious seasoning (India, Middle-East, Mexico) depending on your family preferences. Standard or fancy crudites and good dips. Again - easy, nutritious, child- and adult-friendly.

Boeuf Bourguignon makes for a festive and impressive main course and it freezes really well. Can't go worn with the Classic Julia Child recipe...You can make it up to several weeks in advance and then reheat in the oven or a crockpot.
I hope you can make this a potluck!
