Lime Bars with Walnut-Graham Cracker Crust

For some reason, I tend to shy away from recipes that call for graham cracker or any type of cookie crumbs.  It's probably because I know it will require me to break out my ear-deafening food processor to crush the cookies/crackers.  But when this lime bar recipe landed in my inbox recently, I just had to bite the bullet and make them.  I know, poor me.  

This recipe is a tad different than most since it combines nuts along with the graham crackers for the crust -  it comes together super-quick in the processor.  The original recipe calls for pistachios, but I'm all about using ingredients I already have so I subbed them with walnuts instead.  Any nut would work here - they give the bar an extra crunch, complementing the creamy lime & condensed milk filling.  

These bars are so simple, yet rich - the perfect treat to whip up for a refreshing preview of summer.
