You but you usually get way more. You can get actually deli style sandwiches for around the same price.
I usually opt for a turkey/swiss/lettuce/russian dressing hero. 
Or you can go to the deli at the grocery store, taste test the meats, pick what you want
and make your own on the cheap.
But, I have to say, Subway's breakfasts kick Mcdonald's to the curb (I'll still get the Mcskillet Burrito)
the only thing better was where I used to work where a former PL used to make huge ass omlets or big as shit pancakes, with home fries, and bacon or sausage, all for 2.99, yes 2.99.
No one can beat that.
