Some days when I forget to bring lunch to the mountain and I'm really hungry I make some ghetto ass food out of the free shit in the lodge.
One of my favs is to get some hot water from the food court and sqeeze a bunch of ketchup into it. Add some salt and pepper stir it around and it makes a pretty legit tomato soup. Don't hate till you try it, it tastes alot better than you'd expect. Then grab a bunch of the soup crackers and you're in business.
At some mountains they have cream cheese and jam for bagels and shit and you can load up on that and put it on crackers. Pretty damn good.
If you get creative you can have a pretty decent meal at the mountain without paying the retarded prices.
