verb agreement

[Sydney]

I would like to know which one of the following sentences is correct and why?

In the trolley are cheese, ham and two loaves of bread.
In the trolley is cheese, ham and two loaves of bread.

Many thanks.

The underlying sentence is this:

"Cheese, ham and two loaves of bread are in the trolley."
The subject of the sentence is "cheese, ham and two loaves of bread". That's plural, so the verb form has to be "are". I'm making the verb blue, because it belongs to the subject.
(If by "trolley" you mean what Americans call a shopping cart, I think you need to use the preposition "in". If you use "on", it sounds like the groceries are passengers on a tram.)

Someone has taken the prepositional phrase "in the trolley" and moved it to the front. This makes the verb go up in front of the subject, but it still belongs to the subject.

In the trolley are cheese, ham and two loaves of bread
