use invocable method to generate dynamic options in visual workflow

I currently have an invocable method being called by a flow. the invocable method return a List<List<String>> in order to send back a list of options, in this case paper types, in a specific order. The flow gets this list returned as a Collection, but I need it to be a dynamic list of options.

Does anyone know how to convert the Collection to this or have my invocable method return this type to the Visual Workflow?

I figured something out for it, but I honestly don't remember what I did. Sorry!
