Drain cans with tuna well. I usually press hard onto the lid while draining the can completely.
Transfer to a large bowl and separate into flakes with a fork.
Add pickles, celery, red onion, garlic, lemon juice, salt, pepper, yogurt and mayo.
Stir well with a fork and refrigerate.
Serve cold in a sandwich or over lettuce leaves.

Notes
Make ahead: Tuna salad tastes best cold. For best results, refrigerate 30 minutes before eating.
Store: Refrigerate tightly covered for up to 5 days.
What canned tuna to buy? I buy canned light tuna packed in water. Albacore tuna has less "fishy" taste and white "meaty" texture or yellowfin/skipjack/light tuna is tan to pink in colour and has more strong fish taste. I always buy chunky one vs. whole because it's cheaper.
Mayo + plain Greek yogurt: I used mayo made with avocado oil and Greek yogurt with at least 2% fat for the tastiest results. You can omit mayonnaise though.
