Cucumber Dill Avocado Tuna Salad - a healthy, mayo-free tuna salad perfect for lunch

I’ve never really considered myself particularly talented in the lunch department, but I daresay there has been some improvement over time. It used to be I’d scrounge for random odds and ends, often eating leftovers from the previous night’s dinner, or drinking a big smoothie, but I’d often find myself starving by 3pm.

After reading countless studies that we should be tapering our meals, eating more food in the morning and afternoon than at night, I’ve finally gotten better about prioritizing the lunch meal.

My usual for the mid-day meal is a big veggie stir fry, tuna salad on toast, or a big, colorful green salad. Tossing together a nice mayo-free avocado tuna salad is mega for keeping me full until dinner time, as I find protein and fat to be highly satiating.

Recipe Adaptations:

  • If you don’t like avocado or don’t have access to avocado, replace the avocado with 1/2 cup of mayonnaise of your choosing. I like using avocado oil mayonnaise!
  • This recipe is super adaptable to all your whims and desires. You can add all sorts of fresh seasonal veggies (just chop them up real small), seasonings, even nuts and dried fruit.
  • For another variation upon this recipe, take a look at my Avocado Pesto Tuna Salad with Sun-Dried Tomatoes. 
  • Not a fan of tuna? You can use this recipe as inspiration for chicken salad!

You can eat this tuna salad on top of toasted gluten-free sandwich bread (which is what I usually do), eat it just as it is, or plop a dollop of it on top of a green or grain salad.

That sounds delicious and refreshing with the cucumber and dill! Love that it's mayo free of course! I'm also not very creative in the lunch department. I just stick to the same things every week, but it works ;)

I now have a new lunch goal! This sounds awesome--I detest mayo so I'm loving the avocado in there :)
