Clean Eating

Has anyone tried clean eating?  If so, I welcome any tips and ideas on how to make it work for me.  I already eat pretty healthy, I just still eat alot of processed foods so I want to eleminate that as much as I can.  If you have any tips, recipies, good websites or any info on the subject, please let me know....I'd love to learn more and think I may be giving "clean eating" a try next week. :)  Thanks!!!  ~Kendra~
