Answer:
None.
Step-by-step explanation:
A dependent clause is a group of words or phrases that do not make a complete thought and cannot be used or taken as a complete sentence. To be a complete sentence, it needs an independent clause.
In the given sentence, there are two independent clauses with no dependent clause. the independent clauses are "my father cooked spaghetti for dinner" and "I made the salad and garlic bread". And with the use of the coordinating conjunction "and", the sentence becomes a compound sentence.
Thus, there are no dependent clauses in the given sentence.
