I’ve tried various things from ghost kitchens via Door Dash. Some are better than others.

From the little I understand, someone like Beast Burger would come up with a recipe, then provide the supplies and recipes to the ghost kitchen to make it. If the ghost kitchen is really Chili’s, it’s not the Chili’s burger showing up when a Mr Beast label, it’s Chili’s Employees in the Chili’s kitchen, making the Beast Burger recipes.
