Mayo makes many salads unhealthy, that's why I am so excited to find tasty recipes without it! This one is tuna based and u can change the flavor shy adding or subtracting more vegetables and seasonings.
There are other variations of this recipe on the blog. This is the basics of the recipe I have tried and loved so far. A lot of the ingredients you can eyeball. I truly love putting more rice vinegar in it!
core recipe is:
1 2-to-3 oz. package of tuna
about 1/2 c. of diced onion (but you can eyeball* it)
1 T. of lemon juice or rice vinegar
2 to 3 T. of olive oil (use 2 if the tuna is packed in oil; 3 if it’s packed in water)
1/4 c. chopped parsley – again; just eyeball* it
1/2 to 1 whole avocado
1/2 t. kosher salt (or 1/4 t. regular salt)
1/4 t. fresh ground black pepper – or more to taste
If you want switch out the parsley for cilantro and lemon juice for lime and make it taste more Latino. Yum!
