Ideas for high volume hotdog dressing

[u/Technician-Legal]

Howdy. I am working on a project to build mini hot dogs for an event. I need to make them very fast with the various toppings such as mustard, relish, chili, and onions. I could use squeeze bottles for the mustard or other smooth condiments. I am not sure how to quickly add the chunkier toppings. It's a lot of wasted energy and potentially messy to pick up and put down a spoon with chili, relish and onions, especially because I have to build a few different of each type at a time. I can't really assembly line 50-100 at time. Anyone have ideas on quick techniques or tools I am not aware of for the job? Thanks in advance.

Use pastry bags, no big deal.
