Sunburst Chart - Subcategories

I've been tasked with a work project that involves creating a diagram outlining all of our workplace's features and benefits in one place. The idea is that the features are in the middle with the benefits moving to the outside.

I have used a sunburst chart to visually demonstrate the early drafts of this model, however I am unable to find a way to add sub features. 

Below is a simple demonstration of what I would like using every day meals. The types of food are in the middle, with the benefits on the outside. 

This is all well and good, but consider there are two very different types of Pizza - a high quality restaurant pizza, and a store bought frozen pizza. Both come under pizza, however have different benefits. 

Is there a way, I can add the different categories of pizza into the same wedge? I still want pizza as the overall category, and it is essential that all the benefits remain in the same layer. 

This is the current table.

And below is what I hoped would work - and if the above information wasn't clear, what I want the end product to look like. 

I know this is not what the graph was intended for however I'm not a graphic designer and the chart is so effective at showing a large amount of information! In my work example, There are currently 100s of rows and 6/7 columns. It needs to be condensed to about 4
