How to make Tuna Avocado Salad
- Prepare the tuna – I start by draining the canned tuna really well so the salad stays creamy instead of watery. I place it in a mixing bowl and gently break it into bite-sized flakes with a fork, leaving a little texture rather than mashing it completely.
- Mash the avocado – In a separate bowl, I mash the ripe avocado until it’s mostly smooth with a few small chunks left behind. Those little pieces make the salad feel fresh and give it a more satisfying texture than a completely smooth mixture.
- Create the creamy base – I stir the mashed avocado together with the Greek yogurt and mustard until everything is well combined. The avocado adds richness, while the Greek yogurt keeps the dressing light and creamy without needing mayonnaise.
- Bring everything together – I fold the creamy avocado mixture into the tuna, then add the finely chopped red onion, bell pepper, and celery. I mix gently so the vegetables stay crisp and every bite has a little crunch.
- Season to taste – I finish with salt and freshly ground black pepper, then taste and adjust the seasoning if needed. If I’m using fresh parsley, I stir it in at the end for a bright, fresh finish.
- Serve your favorite way – I enjoy this tuna avocado salad right away while the avocado is at its freshest. It’s delicious spooned onto toasted whole-grain bread, tucked into lettuce wraps, served with crackers, or piled over a bed of greens for a quick, satisfying lunch.
