Average Food Costs
Is there a reference sheet or a general guide for food costs. I don't mean on how to calculate your own food costs, but a guide or index of what known common food costs are.
For example : its known that a hamburger in actual food, costs McDonald's .34 or that a BigMac is .77 I'm curious if there is a rule of thumb for an omelette or macaroni and cheese or a chicken sandwich.
Yes, I realize that a two egg omelette vs a four egg, or cheap cheese vs. good cheese or the size of the portion for the mac and cheese all plays a part into what food costs end up. That's why I'm asking for a general generic guide.. or a lists of averages. That's what I'm looking for.
