Toffee Pecan Cookies

I bought a package of Heath toffee bits back in December and didn't get around to making anything with them until this weekend. I should not have waited so long! These sweet, chewy cookies get a nice crunch from the pecan pieces. To me they tasted better the next day. I still have more than half a bag of toffee pieces and can't wait to use them! Do you have a favorite recipe with toffee?
