With crunchy lettuce and spicy mustard, these sandwiches are addictive! They are packed to the edges and nutritious! And, on top of that, they take very little time to make!
These are better than those sandwiches sold at convenience stores!
After washing the lettuce, pat excess water from the leaves with a paper towel. Go easy on the mustard powder if you are making them for kids!
