Hello, all. Looking to be a food vendor at an upcoming community event. All proceeds to go to charity.
Idea is burgers. Classic, smashed on a rented large griddle. Plan for ground chuck. Salt and black pepper, Martin's Potato Rolls. American cheese, and a sauce, other toppings standing by (onions, tomatoes, lettuce). May consider not offering ketchup and mustard, but we'll see.
Any tips? I've never done this before, so looking for any advice.
