Sheesh. That combination, I might ask them to bring their own food!

A nice wild rice recipe would be great for the vegetarian.

Pumpkin seeds would be a wonderful addition to your vegetarian meal. It is seasonal and provides protein.

Thanks so much! Very good ideas.

haha- this sounds like some of our family dinners-- there are years when Easter and Passover overlap and it's culinary mayhem. :) I would say that you should find out if the kosher person is hardcore kosher or kosher style- if they are just Kosher style, then you will be able to serve them many of the same foods as long as you don't mix meat and dairy, or involve shellfish or pork products. So, they could eat the same dressing, for example, if you don't put butter on it, or flavor it with sausage or bacon or something. I would probably make the dressing outside of the bird, and maybe use vegetable stock instead of chicken stock, then maybe everyone will be able to enjoy it . . . You can use some walnuts or chestnuts and maybe some raisins for added flavor . . . Same thing with the Turkey, you can put olive oil on it with herbs and spices, instead of butter or salt pork or something . .. maybe a nice fresh salad with cucumbers, red onion, lemon juice, olive oil, salt, and tomatoes or cherry tomatoes, and some dill . . . If you serve lots of vegetable dishes and don't add butter or chicken (or other meat) stock to them, everyone should enjoy them . . . For the veggie, you could also do a stuffed pepper dish or something that won't require a ton of separate work . .. often, if you have plenty of vegetarian side dishes, they might not care if their isn't a specific "main dish" . .. hope this helps!

There's a barley pilaf recipe I'm fond of here: http://kayatthekeyboard.wordpress.com/?s=barley+pilaf. If you want to make it a kosher dish, sub margarine or some such for the butter. Black bean cakes are a good protein; cook your black beans with whatever seasonings you wish, drain and mash, and form cakes; dust them in cornmeal and fry.

Thank you--that's helpful.

For the diabetic and the person who keeps kosher, I'd ask for direct suggestions. You want to keep people safe and to respect religious preferences, and it's difficult to know what someone's specific restrictions are without asking.

For the vegetarian (and everyone else): a simple dish of roasted fall vegetables (sweet potatoes, celeriac, parsnips, fennel, red onion, garlic, any squash), cubed and tossed with a few tablespoons of coconut oil, is easy and good. I'd also try to be sure that you have some sort of protein for the vegetarian, so include something with nuts or beans. You could do something as simple as adding nuts to the wild rice (almonds, pecans, cashews) or do the couscous recipe (though I often find that people are averse to pistachios more than other nuts, for some reason). Or perhaps a chickpea dish (Indian spices, like this: http://www.nytimes.com/2009/03/04/dining/041vrex.html?ref=dining or just do Bittman's terrific roasted chickpeas: http://markbittman.com/dinner-with-bittman-roasted-chickpeas).

Inexperienced eater - the turkey and maybe some simple mashed potatoes are always safe, I'd think.
