High-Protein Tuna Stuffed Avocado — 34g Protein, Under $4
This is the kind of lunch that photographs so well people assume it came from a trendy health café. Half an avocado filled with a herby, lemony tuna mixture — canned tuna, Greek yogurt instead of mayo, red onion, celery, and fresh parsley — sitting in its own natural shell and ready in under five minutes. No cooking, no heating, no equipment beyond a bowl and a fork. The Greek yogurt keeps it creamy and adds protein without the heaviness of mayonnaise, and the combination of tuna, avocado, and yogurt pushes the protein count to 34 grams in a lunch that costs under four dollars. Simple, clean, fast, and visually stunning every time.
Ingredients
Method
- Drain the tuna thoroughly and add it to a small bowl. Flake it apart with a fork.
- Add the Greek yogurt, diced red onion, diced celery, fresh parsley, lemon juice, salt, pepper, and red pepper flakes. Mix until fully combined.
- Taste and adjust seasoning — a little extra lemon juice often lifts it further.
- Halve the avocado and remove the pit. If the hollow left by the pit is small, scoop out a little extra avocado to create more room for the filling.
- Spoon the tuna mixture generously into each avocado half, mounding it slightly above the rim.
- Top with everything bagel seasoning, capers, or extra parsley if using.
- Serve immediately with a lemon wedge on the side.
Notes
Canned tuna in water is one of the best protein-per-dollar foods available in any grocery store — buying a multi-pack brings the per-can cost down significantly. Greek yogurt replacing mayonnaise not only cuts fat but adds meaningful protein, making this swap one of the most effective macro improvements in budget cooking. Avocados bought when slightly firm and ripened on the counter at home are almost always cheaper than buying ripe ones from the store.
