There are many different ways to submarine sandwich.

But, the possibilities really are endless and cover every variety of meat available frommeatballstoroast beefto chicken.

I will be the first to admit that tuna has never been my prime sandwich choice.

I tend to prefer chicken salad over the tuna rendition.

Here’s how each tuna sub ranked in descending order, from my least favorite to the overall best.

For a long time, Subway’s tuna was served up with a side of controversy.

I jumped into the deep end and ordered the 6-inch tuna sub to find out.

The look:Tuna salad sandwiches aren’t winning any beauty awards in general.

But, this mixture’s pinkish-gray hue was extra off-putting.

The taste:Mixed solely with creamy mayonnaise, the tuna salad leaves much to be desired.

The flavor isn’t offensive, yet distinctly fishy and very similar to that of oily canned tuna.

For me, though, it comes off not necessarily as bad but just blah.

It’s made with 100% albacore tuna, also referred to as white meat tuna.

The smallest “skinny” size cost me $5.89, though original and big sizes are also available.

The look: Crackly, dry-looking bread is a common theme with Potbelly’s subs.

On the inside, though, the tuna salad looks creamy and chunky, albeit slopped on sparingly.

Tomato slices are thin yet wide and lettuce shreds fill in all the nooks and crannies of the sandwich.

My larger issue with the sandwich is that it needs more zhuzh overall.

Everything falls a bit flat with muted flavors across the board.

The look:Like most of Jimmy Johns' sandwiches, it’s bread heavy.

Lettuce was hard to come by but I counted three tomato slices and five cucumber slices lining the hoagie.

The taste: Filling with a flavorsome tuna salad iteration.

This fact doesn’t detract from the overall experience, though.

Everything still melds well with the soft and fluffy bread and the crisp lettuce and tomatoes.

But, it loses some of its sliced-right-in-front-of-you, fresh meats power in a creation like its tuna fish.

As I ordered my sandwich, I elected for a mini size on white bread for $6.95.

The look:Short but stout, packed with plenty of vegetables.

Underneath all the rest though, there is a messy splatter of pale pink tuna salad.

The taste:Well-rounded in terms of taste and texture.

I found this sub to be quite appetizing and it all started with the fish amalgamation.

The tuna isn’t anything overly specialperhaps a step up from canned.

But, as a whole, it’s juicy without being bogged down by mayonnaise.

In fact, it’s the only sandwich on the menu listed as a certified “cold sub.”

The chain shares that its tuna salad consists of tuna, relish, mayonnaise, and black pepper.

My small order, which equates to about a 4-inch sub, cost $5.99.

The look:More of a snack-sized sandwich.

I just wish there was a tiny bit more of the pepper-speckled concoction scooped on.

The taste:Firehouse to the rescue!

This is the last tuna sub I tried and it did not disappoint.
