Food brokers are the companies a lot or maybe most commerical kitchens/restaurants buy their foods, supplies. Different compaines provide various ranges of products and services. So I am sure certain brokers would have a good range of job opportunities. Some brokers hold classes for food safety, have marketing, sales, delivery and etc. Could get you into a lot of restaurants and networking with folks in the industry, while paying the bills and getting a feel of what might really be a fit for you.
Sysco would be one of the big companies, US Foods.
There could be some smaller, local companies in your area, and those may also specialize in one area, i.e. produce, meat, chicken, etc.
