Chain stores that are only near you.
I believe Amato's is only in the north east but they are a great price for good food.
This is "The Original" sandwich but from a gas station though branded from amato's. There are also full normal amato's restaurants around and they have hot food ready to go you just grab.

$7, It was really good.
These are their "stuffers" (jesus)

They're my go to usually and are normally in the hot food spot so you just grab em and buy them. You dip them in marinara. You buy them either by either 6 or 12 $7 or $11 but they're hefty, you only want to eat 6.
