Eating is a spiritual experience.

When you eat with correct thought in advance to the mitzvot that you are fulfilling with this food, you are doing something extremely spiritual.  Eating is a spiritual experience because the food becomes a part of your essence.  How we eat elevates the essence of our body and helps us to connect to Hashem.  We become holy by knowing that what we eat has an effect on our soul. Every time that we eat we can say a short devar Torah to elevate the spiritual environment at the table.  If we can not do it at every meal, we can do it on Shabbos.
