At work today--yes, I'm a USAian, and yes, I worked on the 4th of July (double overtime is definitely VIP quality), we had a BBQ-themed potluck.

I brought in BBQ chicken breasts, BBQ beef ribs, and BBQ pork spareribs in homemade BBQ sauce, and everybody liked them.

Other co-workers brought grilled chicken, grilled steaks, a rice and onion casserole (a fairly good one, too) and a chocolate cake.
