This is a family favorite and in frequent rotation during the summertime in our household (Gotta love it anytime DH grills up dinner). Although normally we use sprouts ( Broccosprouts whenever we can find them), the kiddos are more inclined to sub lettuce and omit the tomatoes. Sometimes an avocado can garnish, normally that is on the side as guacamole with chips. Garnish varies depending on what looks good and fresh at the market. **Rudy's BBQ Sauce from Texas is KEY to the flavor of this sandwich! We use all sorts of other sauces, but Rudy's is just the best for these -by the case I tell ya!
