how many calories is a firehouse subs sweet and spicy meatball sub without the bread?

For the Sweet & Spicy Meatball at Firehouse Subs, the full sub is listed at about 480 calories for the small , 880 for the medium , and 1,380 for the large.

Without the bread, the calories would be lower, but there isn’t a published official “no bread” calorie count in the sources I found. A reasonable rough estimate is that the filling alone is around 300–400 calories for the small version, depending on how much sauce and cheese stays with it.

Quick estimate

• Small, no bread: about 300–400 calories.
• Medium, no bread: about 700–800 calories.
• Large, no bread: about 1,100–1,200 calories.

The biggest calorie driver after the bread is the meatballs, cheese, and marinara, so removing the bun cuts a meaningful chunk but not the whole sandwich.

Why it’s an estimate

The available nutrition listings give totals for the complete sandwich, not the filling by itself.

So the no-bread number is best treated as an approximation rather than an exact label value.

TL;DR: A Firehouse Subs Sweet & Spicy Meatball sub without the bread is probably roughly 300–400 calories for the small , with larger sizes scaling up from there.
