This is a very unique sandwich. As 2Bleu said, there are tons of different flavors going on here. I omitted the salt, as we generally find that worcestershire sauce has plenty for us. I used a mesquite smoked turkey breast for a little extra kick. We had never tried fresh tarragon before, so that was the only hanging up point. I thought it was just fine mixed in with the other ingredients, but FI didn't like it. But he asked for the sandwich to be made again soon, without it! Thanks for sharing.
There's a lot of different (yet delicious) flavors going on in this sandwich. I made it for DH for lunch today as he loves avocados. I used chopped jalapenos for the chilis but otherwise made as directed. Thanks for sharing the recipe. :)
