Note: The tapenade can be made in advance and stored in the refrigerator for up to one week.
Add the first 4 ingredients to a food processor or combine with a mortar and pestle. Mix them enough so that they begin to form a paste, but not so much that there are not still small chunks of olive and artichoke.
Spoon the mixture on top of one of the bread slices. Add the feta cheese, lettuce, and tomatoes. Place the second slice of bread on top and put the sandwich in the toaster until the bread is browned. Remove and eat immediately while hot.
