โ Ingredient Notes
- Frozen Mixed Vegetables: Carrots and corn are easy and convenient.
- Red Onion: Thinly slicing is key for flavor without overwhelming.
- Balsamic Vinegar: Adds a tangy, rich depth. You can substitute with red wine vinegar or apple cider vinegar if needed.
- Oil-Packed Tuna: The reserved oil from the can gives a rich, savory boost to the dressing. If you only have tuna in water, use a bit more olive oil to make up for the flavor.
- Red Kidney Beans: These are hearty and protein-rich. Black beans or chickpeas work well as substitutes.
- Red Chili Peppers: Add heat and flavor. Adjust the amount to your spice tolerance, or swap for crushed red pepper flakes if youโre in a pinch.
- Flat-Leaf Parsley: Fresh and herby. If youโre out, try sage or tarragon for a different flavor profile.
- Dijon Mustard: Brings a subtle kick and ties the dressing together.
- Extra Virgin Olive Oil: Use a good-quality oil for the best taste, as it makes the dressing shine.

๐ชHow to Make Spicy Tuna Salad
Microwave the frozen mixed vegetables until crisp-tender and set aside.
Soak the sliced onion in vinegar and water for 5 minutes, then drain and dry.

Mix the veggies, tuna, beans, chili peppers, pickled onions, and parsley.

Whisk the vinegar, salt, pepper, garlic, and mustard. Slowly add olive oil and reserved tuna oil.

Toss salad with dressing and serve. Enjoy!
๐จโ๐ณPro Tips
- Reserve Tuna Oil: Use some of the oil from the canned tuna in your dressing. It adds a rich, savory flavor that enhances the salad.
- Microwave Veggies Just Right: Cook the frozen mixed vegetables until crisp-tender to retain a nice crunch and avoid sogginess.
- Pickle Onions for Flavor: Soaking the onions in vinegar and water mellows their sharpness, making them more pleasant in the salad.
- Donโt Overdress: Start with a little dressing and add more as needed. You can always add more, but you canโt take it away.
- Adjust the Spice: If you like a lot of heat, keep the seeds in the red chili peppers. For a milder salad, remove the seeds or reduce the amount of chili.
- Chill for Better Flavor: Let the salad sit in the refrigerator for at least 30 minutes before serving. This allows the flavors to meld and makes the salad taste even better.
- Serve Fresh: This salad is best enjoyed fresh. If making ahead, keep the dressing separate until ready to serve to maintain a crisp texture.

๐๏ธStorage
Got leftovers? Store in an airtight container in the fridge for up to 3 days. For max freshness, keep the dressing separate if youโre meal-prepping. When youโre ready to dig in, give it a quick toss, and youโre good to go with a flavor-packed meal anytime!
