So, I made this recipe with half the calories listed. I used low calorie bread (35cals/slice) and I used 1 wedge of laughing cow cheese (30ish calories) per sandwich. I also bough pre-sliced thin chicken. It was a bit expensive but saved me a little time. I also used sun-dried tomatoes instead of fresh. All in all, my sandwich was about 200 calories.
The jalapenos added just the right kick to this sandwich.
