A direct object is a part of a sentence, and not a part of speech. Dinner is a noun. Whether or not it is a direct object depends on how it is used.
"Dinner was good."
Here, dinner is a subject. (Something was good. What was good? Dinner.)
"I ate dinner."
Here, dinner is a direct object. (I ate something. What did you eat? Dinner.)
"I like eating cashews with my dinner."
Here, dinner is the object of a preposition. (I ate cashews with something. With what? With dinner.)
As you see, nouns have many uses in the English language, and a direct object is but one of them.

There is one direct object, which is the phrase "a lunch or dinner of worms". The structure of this direct object phrase is: article ("a"), noun ("lunch or dinner"), noun complement ("of worms"). The noun plus noun complement is a shortened version of "lunch of worms or dinner of worms". The "of" phrases express the logical objects of the verbs corresponding to "lunch" and "dinner", namely the verbs "lunch" and "dine". Thus, another way of expressing the same thought would be: "Most fish enjoy lunching on worms or dining on worms."
