Carol,
any Jam and combination of chopped nuts works great!
Pecans or walnuts are really tasty... even toasted pine nuts!
I think almonds are just the standard...
I, personally, like baked brie sweet, but savory baked brie (mushrooms, sweet onions, veggies) is also nice...
you can also get creative by adding a tbsp of sherry, marsalla, cognac, etc. to the whole mix...
Baked brie is a good place to experiment with ingredients!
