creating a Bill of materials or something similar (total noob here)

Hello,
I have excel through office 365 so the latest version I guess.
I would like to create "Something" not sure whats its called.
Where on sheet 1, I can havea list of items and their prices...
then on the second sheet, i have those items listed but I tick a box for the options I want, and then there would be a "totals" column that gives me the end price.
Also in this, there would be provision to have a product, that includes more then 1 item. SO apart from the listed items... lets say, apples, oranges and bananas, on the second sheet I would have a product called "Small Picnic" which woudl just include the Apple and Oranges price. but I would also have "Big Picnic" which would include Apples, Oranges & Bananas

I hope all that makes sense... I am willing to read tutorials or so forth myself to work it out, I just dont know what im looking for, so if someone could point me in the right direction it would be greatly appreciated.

Cheers
