Drain tuna, squeezing as much moisture out as possible then set aside. In a medium mixing bowl, add avocado. Mash until nearly lump-free—you should have approximately 2 Tbsp of mashed avocado.
Add yogurt, lemon juice, seasoned salt, garlic powder and dried dill. Mix until completely combined then add green onion, celery and drained tuna. Stir until combined. Season to taste with salt and pepper.
Cover and chill until ready to serve. Enjoy!
Notes
Solid white albacore is a bit more expensive but retains much less liquid and works better overall. You can really taste the difference!
