Take a look at the sentence again:
Todd is an amazing cook, he can look into a nearly empty refrigerator and
put together an interesting dinner; yesterday, for
example, he made a sliced pickle and mayonnaise
sandwich, using an old blueberry muffin as bread.
The comma between example and he is necessary. For example is an introductory transition. He made a sliced pickle and mayonnaise sandwich is a main clause. When an introductory transition begins a main clause, you need to connect the two with a comma.
