Something Delicious, Fast and Easy...?

I'm going to Handsome's show tomorrow night but I'm also meeting up with 5 of our friends for a pre-show appetizer/wine sort of gathering at one of their houses.

Everyone agreed that they would bring "something" and since it's my husband they are going to see, I sort of feel obligated to go beyond chips/salsa.

I'm also a Pretty Party Hostess Perfectionist. I'm addicted to recipes and everything bores me in my recipe box.

Anybody have any sure fire hits for these sort of things?

If not, here's what I'm thinking about making:

Plum Tomato & Pesto Bread


Prep Time:10 min
Total Time:30 min
Makes:
24 servings, one slice each
1 loaf (1 lb.) Italian bread, cut in half lengthwise
3/4 cup pesto
6 plum tomatoes, sliced
1/2 cup sliced pitted ripe olives
2 cups KRAFT Shredded Mozzarella Cheese
1/2 cup DI GIORNO Shredded Parmesan Cheese
PREHEAT oven to 400°F. Place bread, cut-sides up, on baking sheet. Bake 8 to 10 min. or until golden brown.
SPREAD bread halves evenly with pesto; top with remaining ingredients.
BAKE an additional 8 to 10 min. or until cheeses are melted. Cut each bread piece into 12 slices. Serve warm.

So, guys, suggestions would be lovely. I know there are great cooks out in the blogosphere that have to have better ideas.Help please!
