I love the idea of dressing up your spinach dip!!
But if you're still wanting to do something different, this is a pretty easy but very elegant and really delicious dish.
Brie en Croute. http://www.puffpastry.com/recipe/23992/brie-en-croute?pd=yes
It might look intimidating but believe me, it's easy. All you do is let the dough thaw (overnight in the fridge or for something like 20 minutes before using -- check the package for the exact time) then roll it out a bit. Lift up the dough from where you rolled it so it won't stick to that surface. Then here's what I do:
I put a layer of jelly (a spicy sweet works best, something like strawberry-jalapeno, but really, any jelly works), then a layer of chopped pecans, then lay the brie on top of that. Then top with more nuts and jelly. Then wrap up the dough. It doesn't have to be pretty at all because that wrapped part is the bottom.
Flip it over carefully (but really if it tears, just mush it back together to repair it - it's very forgiving). Then bake as per instructions on the link.
I don't bother with the egg wash and I never decorate with pastry scraps because I don't bother trimming it. As I said, no one sees that bottom part so it just all gets folded over and mushed together.
It takes about 10-15 minutes to put this together. It looks great and tastes great and seems very elegant and gourmet.
