What is the best kind of tuna to use for tuna salad?
There are many options of canned tuna but they are not all created equally. When you are buying canned tuna, be sure to check the ingredients! You want to make sure the only ingredients are tuna, water (or olive oil) and salt (optional).
Focusing on sustainably caught, low mercury fish is also important to me!
To find if the fish is caught sustainably, look for pole caught, line-caught or troll-caught on the label specifically.
Skipjack tuna has much less mercury than albacore or yellowfin tuna. However, skipjack does have a stronger fishy taste. If you want to eat albacore or yellowfin tuna, you may want to limit your consumption to once or twice a week.
What are the best brands of tuna to buy?
- I really love Safe Catch (which has the lowest level of mercury of the market), Wild Planet, Thrive Market brand and Trader Joe’s brand.
- You can find Safe Catch and Wild Planet in most grocery stores, Whole Foods, Amazon and Thrive Market. If you are interested in checking out Thrive Market, you can get 25% off your first order!
What makes this recipe so healthy?
- Avocado– Avocados are nutritious, delicious and they’re a good source of monounsaturated fat and fiber.
- Bell Pepper– The bell pepper adds crunch and a little sweetness, and they’re packed with vitamins (specifically high in Vitamin C) and low in calories!
- Cauliflower Rice– Struggling to get your veggies in? Adding riced cauliflower to dishes like this was an easy way to increase the veggies without ever tasting it!

How to make tuna stuffed peppers
Step 1: In a bowl, cut avocado in half, scoop out half of the avocado into a bowl and mash the avocado. (Can use the whole avocado if doubling recipe, to keep the other half of the avocado from discoloring, add vinegar, lemon or lime juice, and store in the fridge).
Step 2: Add the red onion, cilantro, salt, paprika, cumin, and garlic powder to the bowl and stir until completely blended.
Step 3: Add in the cooked riced cauliflower (you can microwave it for 2-3 minutes from frozen) be sure to let cool. Next, add cooked (cooled) rice into the bowl with the avocado and spices.
Step 4: Drain the tuna (in water) and add to the bowl with the avocado mixture.
Step 5: Cut peppers: To cut the pepper turn it upside down so it sits on the stem. Use where the pepper naturally forms bumps at the top to trace where you should cut to make the cups. Follow the lines down to the bottom. Remove the seeds.
Step 6: Fill the bell pepper cups with the tuna mixture. ENJOY!
How long does tuna salad last in the fridge?
It tastes even better if you let it chill between 30 minutes up to 6 hours. This tuna recipe is good in the fridge for up to 24 hours. You can easily prep and fill peppers the night before for a quick and easy lunch.
Avocado: Prefer traditional mayo in your tuna salad? No problem. You can easily swap out the avocado and use mayo. I like Primal Kitchen because it’s made with quality ingredients and keeps this recipe Whole30. You can also use one single-serving packet of guacamole in place of the avocado in this recipe.
Note: If using a guacamole packet, you may want to reduce adding salt to these peppers.
Cauliflower: you can also use chopped broccoli, shredded zucchini or chopped snap peas to replace the cauliflower.
Peppers: Can use small or larger peppers. You can use any color pepper but yellow, orange and red are the best and most flavorful. If you cannot have peppers or don’t have them on hand, you can also use cucumber boats, collard green wraps or lettuce wraps in place of the peppers.
What are other ways you can serve Mexican tuna salad?
