Labor day weekend--suggestions anyone?

Hello all.

As I've said in previous posts, my weekend overeating hurts me more than anything esle.  With this being a holiday weekend, I am up for  challenge!  Still, some advice about what others have done on holiday bbqs will really help me.

BTW, i'm a vegetarian (not vegan), and will be preparing some vegetarian dishes food for a non-vegetarian crowd on Monday.  I have no problem resisting meat--just portion control.  Add to that the traditional pitcher of party sangria that I bring (and not necessarily have a chance to consume). 

Thanks in advance!
