I second the veggie kababs - with some marinaded tofu (firm tofu cut in to squares and marinaded in soya sauce and sweet chilli plus garlic, ginger ect) then threaded on with all the nice veg. A good sauce is a satay sauce - smooth peanut butter (not sunpat - bleurgh) sainsbury's is good! Mix with soy sauce, soymilk and garlic paste and some ground dried chilli. Very yummy.
Lots of dips and raw veg and breadsticks/homemade soda bread to go with it are crow pleasers.
I would do vegetarian mince pies also - make the pastry with stork, and used veg suet in the mince.
Mulled wine or a coctail with cinnamon in it.
Olives and sundried tomato paste on crostini
selection of grapes and clementines
Chocolate truffles
A big pot of kidney bean chilli with tortillas/rice
Salads like: quinoa and olives/avacado and spinach;
grated carrots and sultanas with some cider vinegar and a pinch of mixed spice;
Tomato slices, garlic, and basil with extra virgin olive oil;
fruit salad with cinnamon
Rice with blackbeans, jalapeno, tomato sauce (from a jar is good) cumin and smoked paprika.
Happy hostessing!
