Ideas...I need a subsitute

Hello everyone!

I'm looking for ideas for something to mix with tuna, or chicken salad and also put on a garden salad since dressings and mayo doesn't sit well, and I find them to dry to eat without anything on them. 

I have been mixing salsa with my tuna

how about yogurt mixed with dijon and a few spices that you like (chives, onion flakes, paprika ...)

I've used lemon before and just for extra taste here is a recipe for Mediterranean tuna salad

Ingredients

• 1 can (5 oz) water packed tuna, drained (if you're not worried about the healthy fat content, get the Italian olive oil packed tuna in jars-- the flavor is terrific!)
• 1 tbsp fresh chopped basil
• 1/2 stalk celery, minced
• 1 finely chopped scallion - green part only (optional)
• 2 tbsp lemon juice, or more to taste
• Extra virgin olive oil to taste
• Salt and pepper to taste

I just use a little 0% plain greek yogurt and a squeeze of fresh lemon with a few grinds of fresh pepper.  

Hummus....I heard it's a great substitute for mayo =) Try to get one with ingredients you can read, lol

One of my kids eats his tuna with mustard, not for me, but to each his own!

Thanks for all the great ideas!  I'm looking forward to trying them :-)
