D.S.
You don't need dip for the fruit. I have done a "fruit salad" for the past 3 years for my daughters' b-day parties, and it is always the first thing to go. I buy red, green, and yellow apples and slice them up and also quarter oranges and throw them in the mix. The kids all love it, and it's cheap and easy.
I have also done pinwheels. Just spread cream cheese over a tortilla and add chopped veggies like carrots, bell peppers and brocolli, add some peas and roll it up. Then just slice up the roll. You could also do variations using a flavored cream cheese. I hadn't thought of it before, but try using strawberry cream cheese and adding fruit for a sweet treat.
I also buy the veggie chips. They come in a big bag at Sam's, and are green, red, and white. The chips are spinach, potato, and tomatoe I think. They are much better than traditional potato chips.
Good Luck and enjoy the party!
