Rio Mare Solid Light Tuna – Simple Canned Tuna That’s Actually Worth Eating

Written By: Andrew Siemon


If you cook at home, you’ve probably grabbed a can of tuna as a quick protein fix. It’s cheap, it’s easy, and it’s often pretty underwhelming. But every now and then you find a canned tuna that’s actually good—the kind you don’t have to smother in mayo just to make it edible.

This post is about one of those surprisingly solid options: a simple canned tuna that comes in both a regular version and an olive oil version, with a thoughtful little thumb tab on the lid that makes it easier to open. You can grab some here on Amazon if you’re interested.

Not gourmet, not fancy—just a genuinely useful pantry staple that tastes good once it hits your plate.


Overview / First Impressions

Out of the can, this tuna doesn’t exactly look like something you’d post on Instagram. It has that typical “canned fish” appearance: a bit pale, packed tightly, and not visually exciting.

But the key thing is this: once you mix it into your food—pasta, salads, rice bowls, sandwiches—it’s actually pretty good. The flavor is solid, not overly fishy, and it works well in everyday recipes.

You can usually find it in two main versions:

  • Standard tuna (typically in water or brine)
  • Olive oil version, which adds a bit more richness and flavor

Both are good, and which one you choose depends on how you’re planning to use it.


What the Packaging Is Like

The packaging has a surprisingly thoughtful detail: a thumb tab on the lid (sometimes called a thumb tab or pull tab). Instead of wrestling with a can opener, you can just:

  • Grip the tab with your thumb and finger
  • Peel back the lid easily
  • Drain and use

It’s a small thing, but if you use canned tuna regularly, this kind of design makes a difference. Less hassle, no need for extra tools, and fewer chances of bending a cheap can opener out of shape.


What It It’s Like

Here’s what stands out:

  • Two main versions
    • Regular tuna (usually lighter and cleaner-tasting)
    • Olive oil tuna (richer, slightly more luxurious, and often better straight from the can)
  • Easy-open lid
    • Thumb tab / pull tab design
    • No can opener required
  • Versatile base ingredient
    • Works in salads, pasta, rice dishes, sandwiches, wraps, and more

How It Tastes & Best Use Cases

Flavor

  • Regular version
    • Mild, straightforward tuna flavor
    • Great when you’re mixing it with sauces, mayo, or other strong ingredients
  • Olive oil version
    • Slightly richer and more satisfying
    • Good when you’re eating it more “as is” (like over rice, in a simple salad, or on toast)

Best Ways to Use It

This tuna really shines when it’s part of a dish rather than the star on its own. Some easy ideas:

  • Tuna pasta – Toss with olive oil, garlic, chili flakes, and lemon
  • Tuna salad – Classic mayo, celery, onion, and a bit of mustard
  • Rice bowls – Over warm rice with soy sauce, sesame oil, and veggies
  • Quick sandwiches – Mix with mayo or Greek yogurt, pile onto toasted bread
  • Simple tuna on toast – Especially good with the olive oil version

Once it’s mixed into something, the initial “meh” visual impression disappears, and you’re left with a genuinely tasty, protein-rich meal.


Limitations / Things to Know

A few realistic points to keep in mind:

  • Doesn’t look great straight out of the can
    If presentation matters, plan to mix it into a dish rather than serve it solo.
  • Not a gourmet product
    This is good everyday tuna, not high-end jarred fillets. Think “reliable pantry staple,” not “special occasion centerpiece.”
  • Olive oil version is richer
    Delicious, but slightly higher in calories and fat. Great if you want more flavor and don’t mind the extra richness.

Final Thoughts

This canned tuna is a reminder that basic ingredients don’t have to be boring. It’s:

  • Easy to open, thanks to the thumb tab
  • Available in both regular and olive oil versions
  • Much better once it’s part of a meal than it looks in the can

If you like having quick, flexible protein on hand, this is the kind of tuna that actually earns its spot in your pantry. It won’t blow your mind, but once you work it into your food, it’s pretty good—and sometimes, that’s exactly what you need.
