Delicious!

I always think savory pastries are good at room temperature, which is why they're so nice for picnics and parties. They're fun to make, but they seem a little special, and they're very satisfying.

These empanadas with potatoes, black beans, spinach and smoked gouda were nice...

These little pear, spinach and blue cheese galettes are lovely at room temperature...

This ring shaped pie with french lentils, chard and butternut squash is nice at room temperature, cut into slices...

As is this with white beans, roasted mushrooms and spinach...

Or there's always a hearty sort of salad, with grains and legumes, like this with wild rice and french lentils, which I served with a cauliflower and carrot puree on the side...

Once again, I've said too much! But I probably have quite a few others that would work!

Jew here! I have a list of "Thanksgiving" salads but they work all winter long and they are delish! http://theglamoroushousewife.com/2012/11/six-thanksgiving-salad-ideas/

I also have two Pinterest boards dedicated to vegetarian dishes that can be made ahead of time: http://pinterest.com/glamorouswife/cooking-salads/ and http://pinterest.com/glamorouswife/cooking-vegetarian-main-dish-and-veggie-side-dishe/

Thanks doll,

Quiche is always good a room temp, if your meal is dairy. Just give it an hour or so to let the chill dissipate after you take it out of the fridge.

I really like this salad served at room temperature:

Excellent question! I made up this little recipe last night inspired by that great post on warm salads from last week. It's really tasty cold!

Roasted Eggplant, Chickpea, Goat Cheese and Wilted Spinach Salad:

I have been dreaming of making a meal out of things on a mezze platter, so I'd go there. Hummus, roasted peppers and carrots, homemade pita, feta, i would probably add some pickled things or fancy olives in there.
