Zaxby's Buffalo Blue Zalad

It is my absolute meal to eat out.  I love, love, love Zaxby's Buffalo Blue Zalad.  LOVE it!  And I have been missing it.  So I got it in my head that I could possible make a decent version at home.  Well, it turned out AWESOME!  And healthier.  Below is a pic of Zaxby's version.

I bought an artisan lettuce box at Aldi.  It included red and green tango as well as oak and gem artisan lettuce (pic below).

I cut up the lettuce and added some baby spinach and I already had in the fridge along with some grated carrots.  I added 2 grilled chicken breast tenderloins that had been soaking in buffalo chicken sauce.  I topped it with 2 tablespoons of low fat blue cheese crumbles and 2 tablespoons of Ken's Chunky Blue Cheese dressing.  I did NOT add the french fried onions that Zaxby's is famous for because I didn't want those carbs or calories.  I was worried that I would really miss them, but I didn't!

My salad was AMAZING!  I made one for my daughter too and she said she really couldn't tell the difference between mine and Zaxby's. Of course, theirs is probably the better tasting, but at least I don't have to continue missing out!

So what was the difference in nutrition info from their zalad to my salad?
