I like traditions as much as anyone but when my friends expect the usual hot dogs and hamburgers for July 4th, sometimes I like to shake things up.  This year, I’m making my Watermelon Mojitos, Grilled Herbed Shrimp with Mango Salsa, Panzanella, and - just to have a little tradition! - my classic Flag Cake for dessert.  It's an easy, summery menu I can make mostly in advance, so all I have to do is throw the shrimp on the grill just before dinner!!  Have a safe and happy 4th of July!!
