values_at method for grocery item is not correct. What am I doing wrong?

I've tried this code a dozen few way including setting the grocery_list = Array.new and adding in the key and value. Nothing seems to work. I just need to know where I'm going wrong.

thanks!

hash.rb 
grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }

if grocery_item.has_value?("Bread")
  grocery_item["food"] = true
end 
grocery_item.values_at("grocery_list" => Array.new)
grocery_list["item"] = grocery_item

Hi Aaron,

The way I did this challenge (and I'm sure there are other ways) is after the 1st task, I first create an empty, new array called grocery_list. I then used the += to add the new 'item' into the new array.

Hope this helps and makes sense. Keep Coding! :)

grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }

if grocery_item.has_value?("Bread")
  grocery_item["food"] = true
end 

grocery_list = Array.new
grocery_list += grocery_item.values_at("item");
