Family reunion what food to bring?

My family reunion is on saturday, and I have no idea what to make for it!
Everyone brings 1 or 2 things, and I always take my friend with me.. well this year she is bringing her husband with her.. so I want to make 3 or 4 things, since there will be...

extra people, not to mention I love cooking!..
I plan on maknig PBJ Cookies, but I want the other things to be food, not dessert, because there are quite a few people bringing desserts {our family loves sweet things!} and I can not think of anything!!

Does anyone have any delicious recipes? I need at least 3 more ideas!

Cheesy Potatoes are always a big hit at our Family Reunions and picnics and super easy to make.

Easy Cheesy Potatoes:
1 bag hash browns, southern style
1 pt. sour cream
1 can cream of celery soup
1/2 stick butter, melted
1/4 c. onions, chopped
2 c. cheddar cheese, mixed in
1 c. cheddar cheese (on top)
1/2 c. milk

Grease oblong cake pan. Spread hash browns in pan. Mix remaining ingredients except 1 cup cheddar cheese. Spread mixture over hash browns and mix well. Top with 1 cup cheddar cheese. Bake at 350 degrees for 1 to 1 1/4 hours.

I've noticed that you may need to cook them a little longer to make sure the hash brown potatoes aren't still a little hard and you can add a seasoned bread crumb topping if you want.

Enjoy!!
