If you are studying this topic, this question is almost too elementary.
number of breads: 5
meats : 6 (what is pulled poke)
veggies : 6
cheese: 6
Source ? : 6
number of possible sandwiches
= 5x6x6x6x6 = 6480
Now the question becomes more interesting if you assume that he may or may not choose any or part of the listing
