Alternative: Tuna Salad

I tend to eat quite a bit of tuna. Mainly because it has a lot of protein, very little fat, and is super convenient. Sometimes I'll stick a can or two in my purse or car if I am on the go. This being said, I hate plain tuna. Makes me feel like I am eating dry cat food...unpleasant. 
Lately, I have been trying a few different mix ins for my tuna instead of using store bought mayo. A few good one's include:

Hummus (pictured above! Very yummy and adds way more flavor then mayo)
Olive Oil & Spices
Mixture of Greek Yogurt, Mustard, and a bit of Vinegar
Laughing Cow Cheese Wedges (would be a good alternative to a tuna melt if you heat it up and put it on some toast)
Homemade Mayo made with Olive Oil

Do you like tuna? What is your favorite tuna mix in?
