Correct understanding and use and of the words in 全都是用爷爷的番茄，生菜和黄瓜做的。

Question

In the sentence 全都是用爷爷的番茄，生菜和黄瓜做的。

全都是 is a adverb to say without exception. 用 is a preposition to say "with" 爷爷的番茄 , is the object 生菜和黄瓜做 ,is the other part of the object and 做的 , is the verb , with 的 at the end to meaning a kind of "made of” Am i right? Im little confused cause 是 and 用 can be also verbs , but that wouldnt make sense with 做 at the end of the sentences and serving as the verb.

Answer 1

全都是用爷爷的番茄，生菜和黄瓜做的。

Here 爷爷的番茄，生菜和黄瓜 is a whole part, replace it with xxx and we get:

全都是用xxx做的

All(全都) are(是) made(做) with(用) xxx.

So the whole sentence be:

All are made with grandpa's tomatoes,lettuce and cucumbers.

The comma "，" might be what confuses you, technically it's incorrect and should be "、", but the misuse is common even among local speakers.

Answer 2

 全都是用爷爷的番茄，生菜和黄瓜做的。

First, the sentence is an elliptical sentence. For analysis, we can add a subject 这些. It's basically a 主(S) + 谓(V) + 宾(O) structure.

So:

Subject(主语): 这些

Predicate(谓语): 是

Object(宾语): 用爷爷的番茄，生菜和黄瓜做的

Adverbal(状语): 全都 (modifying the verb 是)

It's worth to mention that 用爷爷的番茄，生菜和黄瓜做的 as a whole is "的字短语"(的 phrase), which works as a noun. To prove this, we can add a noun word at the end like 用爷爷的番茄，生菜和黄瓜做的东西. In this 的 phrase, 用爷爷的番茄，生菜和黄瓜(with grandpa's tomato, lettuce and cucumber) is an prepositional phrase modifying the verb 做.

For translation, it could be:

(These) are all made by using grandpa's tomato, lettuce and cucumber.

To understand the structure clearly, we can create a simple sentence with the same structure for comparison here. E.g.

这书是用纸做的.

Answer 3

In this sentence, it is used the Subject+是⋯的 structure. Between 是 and 的 you can use nouns, verbs, adjectives, or little phrases, with different meanings.

主+是+名+的。
主+是+动+的。
主+是+形+的。
主+是+小句+的。

In the sentence given, between 是 and 的 we have the verbal phrase 用爷爷的番茄、生菜和黄瓜做 (as imkzh and Jason Swift correctly said, grammar rules would have "、" instead of "，") made of the prepositional phrase 用爷爷的番茄、生菜和黄瓜 and the verb 做 (thank you @dan for pointing this out).

The verb (verbal phrase in our case) in the structure 主+是+动+的 describes or classifies the subject (主).

Edit about the 主+是⋯的 structure
(From the book《现代汉语八百词》. The following list is not complete. It does not include other uses of the structure, including the one for emphasis, each with its own peculiar features.)

Can it be a 主(S) + 谓(V) + 宾(O) structure?

It is not correct to consider 是 as the predicate and 用爷爷的番茄，生菜和黄瓜做的 as the object. That way, we would ignore the very existence of the 是⋯的 structure. As explained in the same book cited above, a 的 phrase ('的'字短语) preceded by 是 forms the 是⋯的 structure functioning as predicate.

Answer 4

全都是 用爷爷的 番茄，生菜和黄瓜 做的。
