Of sorts...
Sometimes it is raw veggies (carrots, celery, red bell pepper, broccoli florets, black olives or some variety thereof), and sometimes it is a variety of sliced cheeses with a variety of crackers, and seedless grapes. Sometimes it is just fruit (apple slices, seedless grapes, strawberries).
No matter what I do though, I never buy O. of those prepackaged ones. They are some of the most unappetizing things I see... and it always seems like someone brings O. when people are expecting they need to bring "something".
The carrots are always dried out or slimy (O. or the other), the apples are brown or mushy, and I rarely see anyone eat any of it. Anywhere.
But if you make a fresh tray at home, people gravitate to it and eat it, in my experience. I know I do. And when it looks like it's a pre-packaged O. that has just been "plated" to look like it was done it home, it doesn't fool me...
