I've got a party to go to and I have to bring something the catch is it's going to have a bunch of vegetarians at it and I don't want to bring a vegetable platter. Please also nothing "Indian" because there's going to be tons of that there already. Also no nuts for allergy reasons. Bonus points for things that include coconut milk as I've got lots of it and it'll help keep me satisfied and not eating all the horrible soy based stuff.
Let's just go with vegan choices as I don't know what these people are willing to eat.
I do eat rice and potatoes at social functions, though not normally.
Chowstalker has an excellent vegetarian section. I don't know if they, or you, are open to cheese.... but they have some really tasty looking goat cheese stuffed baby peppers. I'd go to the farmers market and pick up some really good goat's cheese that morning for this recipe.
Are nightshades and dairy in your diet?
I make a casserole with grilled eggplant (slice and roast or saute first if you don't have a grill), roasted red bell peppers, caramelized onions sauteed in tons of pasture butter, whole-milk mozzarella, and a tomato sauce made with fire-roasted tomatoes (seasoned with garlic, lemon juice, herbs, etc). To me, it's a side dish, and my veggie friends go nuts for it!
I usually eat some protein right before I go out, since most of the time there isn't any at parties I go to - even when they're not vegetarians!
I know you're trying to be compatible but I still don't know how strictly paleo you are...such as if you do dairy since vegetarians (and not vegans) are often okay with it. So this list is assuming that you're okay with dairy. I'm also still not sure if you're okay with starches from tubers or rice (some here are on board, some aren't). So I just came up with a list assuming that you're fine with it all.
Homemade yogurt with fruit
Curry soup with coconut milk and vegetables
Stuffed peppers with vegetables cooked in coconut oil or pastured butter
Souflees with vegetables
Rice stir-fried thai style with spices, vegetables, eggs and coconut milk
Sweet potatoes with butter and/or coconut oil
Gelatin dessert with coconut milk and fruit
Spring rolls with rice paper and nori, eggs, avocado and cucumber
Eggplant dipped in eggs and fried
Fried green tomatoes
Chop up some parsnips into little cubes and steam them. Sautee some onions/mushrooms/garlic/shallots/rosemary in coconut oil/butter and mash them all together. Use a bit more parsnips than other ingredients so it mashes up into creamy goodness properly. You can add a little coconut milk to smooth it out if you need. When you make it for yourself at home, I recommend adding in some bacon for flavor. You can also mash up some spinach in there.
I just made this coconut and green beans..it was yummy! http://www.theclothesmakethegirl.com/2012/03/14/coconut-almond-green-beans/
Okay, since you changed it to vegan dishes, I hope this helps!
