People are actually in this thread discussing how feasible this is as if it were a real plan down to calculating specific costs and supporting them with URLs.
I mean, it's a bummer when the bougie burger places do this, but when the taco trucks and teriyaki shops near me started costing more than $2 a taco or $10 for a plate of yakisoba, I knew shit was getting hard out there.
Makes me wonder what people are paying for bread, Kraft cheese (or a knockoff of the same) and butter/margarine.
Seriously, a single grilled cheese shouldn't be more than $1, it should be much less... At least in materials.... The cost of grilling it and cleaning up and whatnot should still be really cheap. Even if you wrap the sandwiches in wax/parchment paper or whatever and serve it, you should still be able to make a profit per sandwich. Whether you would be better off doing this rather than getting a job at McDonald's or whatever... That will depend on how popular the food truck is....
There used to be a vending machine in a hosiptal near me that would heat up a premade grilled cheese sandwich for £2. Being a vending machine in a hospital, they had to be making at least enough to cover the costs plus wastage. I'd say that somewhere with high footfall, especially on a cold day, you could make at least some profit from this.
Just saying the concept works, ppl DO want a simply Sammy for a buck and the ingredients are less as 30% of sales price even with some real decent toppings. But renovation (and extreme rent) only allows multi nationals to compete at busy places like city central stations etc.
Gaslamp district in San Diego had a cafeteria like this years ago, guessing it's no longer a thing, but simple cheap menu would have steady customers, maybe profitable, it's the business development people who would oppose.
