    Red and yellow peppers sliced and stuffed with tuna salad on a wooden cutting board.

    Skip the fluffed mayonnaise and all the ick that comes with it and whip up this whole30-approved, tuna salad instead.

    Made with a paleo-friendly mayonnaise and seasoned until deliciously savory, these tuna salad stuffed peppers are a wonderful low-carb snack- just like tuna stuffed avocados.

    As a Certified Nutrition Coach, I love how simple this recipe comes together while still giving me a boost in nutrients and energy.

    Whip them up as you need them or prep them the night before for lunch, either way, these stuffed peppers are a recipe you’ll come to rely on.

    Why You'll Love This Recipe

    Easy: Made with only 5 main ingredients and ready in just 10 minutes, this tuna salad is the perfect last-minute lunch.

    Healthy: This recipe uses a whole30-approved mayonnaise that not only taste great but also containers healthy ingredients.

    Meal prep: You can easily make the stuffed peppers a day in advance if you need a super quick lunch.

    Ingredients and Substitutions

    In order for the tuna salad to be Whole30 complainant, you need to use a whole30-approved mayonnaise. I use the mayo from Primal Kitchen as I love the ingredients and it adds a great flavor to the recipe (I use it for whole30 deviled eggs too).

    Make sure to finely chop the cucumber and pickles so that you get pops of flavor in each bite.

    Expert Tips To

    Drain the tuna fully before you mix it, no one wants extra tuna water.

    Whip up the tuna salad and taste test it. Then, adjust the seasonings as per your preferences. I actually like mine with a bit more pickle- add more if this is you!

    How To Make Them

    Step 1: Add all the salad ingredients into a bowl.

    Step 2: Mix until combined, taste test, and adjust.

    How To Store Them

    If you're not going to enjoy the stuffed peppers immediately, store them in an airtight container in the fridge for up to 2 days. Know that the tuna mixture might be a bit more watery after sitting. This is also what you’ll want to do with leftovers.

    You can also store the tuna salad separately from the bell peppers until you need them. If you do this, remix the tuna and adjust any seasonings you need to.

    Flavor Variations

    You can easily adjust the taste of the stuffed peppers with a few simple tweaks. Some reader favorites are below.

    Herbs: Adding in fresh parsley or other greens is a great way to increase the nutrient value and change the flavor.

    Pickled onions: In addition to the pickles, you can sprinkle some chopped pickled red onion into the mixture.

    Cheesy: This can be used either by serving them cold or if you plan to make baked tuna stuffed peppers. Sprinkle your favorite cheese to the top of the tuna.

    Cucumbers: If you’re not feeling peppers, spoon the tuna salad onto thick slices of cucumbers to enjoy it.

    And to finish it off if you need something sweet, whip up these high protein birthday cake balls for a treat.
