Grilled Chicken Sandwich

So on the 4th of July I threw together this sandwich and opted out of the hamburgers and hot dogs.  I was AMAZED by how delicous this sandwich was! It is great way to use left over chicken as well. 

Ingredients:
Grilled Chicken Breast - I put about half of a small chicken breast on the sandwich
Lettuce
Onion
Tomato
Green Pepper
3-4 Tsp of Raye's Mustard - Winter Garden ( at only 5 calories per tsp spread it on! so good)
2 slices of Ezekiel 4:9 Bread (I prefer mine toasted or on the grill)

This is a filling and delicious sanwich at less than 375 calories!
