It is good idea. You asked ahead of time. That is a great sign about you care about what to bring party. You will be a welcomed guest anywhere you go. Fresh cut fruit is good, when I have people come, I don’t always have time to get the best fruit bowl. So, you can buy different fruit at store, then wash and cut. It only takes time to do. You can have watermelon, grapes, strawberry, honeydews or cantaloupes, pineapple, blue berry. Some verity and colorful. Or bring in beer/wine/drinks. If you really want to cook, try your hometown special. When I have party, I enjoy the most is different food from different area. I can cook most common food myself. It is boring to have same food all the time.
