as I understand the regs…if it is precooked/prepared…all your doing is reheating the product…same as a hot dog/brat…the rule is that you can not cook raw food on a cart, if you go into the  “Cook mode” you pull the trigger on the 3 compartment sinks and some other requirements….

With all due respect, I don’t think you are understanding them correctly.  I am not from your state but I have learned much on this forum from other members in other places, Florida included.  From what I have learned you would be in violation.  BUT…….if you do get your HD to approve what you are hoping to sell, Congratulations.    DD
