Explanation:
Rob explained what he liked on his sandwiches to the chef. This is the sentence that uses a noun clause as a direct object. See the underlined structure and the explanation below:
explain(ed) is the main verb and it is transitive; it needs a direct object .
what he liked on his sandwiches is the noun clause. It can be replaced by a noun phrase: this fact - Rob explained this fact to the chef.- ; and what he liked on his sandwiches is a clause because it has a subject and a predicate: he (subject) + liked on his sandwiches ( what -placed at the beginning) (predicate).
