Here's why:
* Linking verbs connect the subject of a sentence to a word or phrase that describes or identifies the subject.
* In this sentence, the subject is "sandwiches".
* The word "delicious" describes the sandwiches.
* The verb "taste" acts as a bridge, linking the subject ("sandwiches") to the description ("delicious").
