Mr. Picky Eater claimed this to be the best sandwich he has had in the US. This is one good sandwich! You can adjust the heat to your taste by cutting back on the chipotles, or adding extra like I did. The recipe makes extra sauce so you may want to cut it in half, freeze some for later or leave it thick and serve some with chips. I'd also suggest adding extra avocado, cause it tastes so good.
