I made a couple of tartlet's and filled then with egg/cheese mix. It wasn't quiche and a few people thought it was too solid (i.e not quiche) but it was supposed to be a cheese tart.

Lightly sweetened goat cheese and (this time of year) apple fig relish. I posted a recipe last month called Chestnut Crackers with Savory Fig Relish, http://www.food52.com/recipes/8097_chestnut_crackers_with_savory_fig_relish which might be of interest. I also posted one for Sweet Holiday Fig Relish, http://www.food52.com/recipes/8095_sweet_holiday_fig_relish , which has a figgy pudding flavor profile. Or, I'd use some Meyer lemon marmalade. Yummm. ;o)

Custards and puddings of any flavor you wish....fruit compotes (even with frozen berries they would be wonderful), mousse of whatever flavor you wish, fresh fruit if you can find it in January and it's flavorful, with a bit of a simple sugar glaze (maybe with some spices to tart it up....a touch of cinnamon, star anise, nutmeg, depends on the fruit), lemon curd, MEYER LEMON CURD (yum), the possibilities are absolutely endless.

You could go savory and do little quiches in them....bacon, carmelized onion, cheese and egg custard.

I like berries, which you can glaze with a cooked-down current jelly.

If you're feeling lazy, just use great jam, topped with a dollop of creme fraiche.

The Lazy Mary's Lemon Tart looks a winner...

You have 3 good suggestions right here! I also like chocolate mousse. Or banana!
