Usually, when there are over-ripped avocados, I'll use them to make guacamole, a dressing, or tuna salad. I brought the avocado tuna salad up a notch to create the perfect lunch by deconstructing it. For example, I separated the usual ingredients in a tuna egg salad: egg, celery, mustard, spices, and scallions.
Then, a poached egg, avocado, and olive oil were used instead of mayo for a creamy texture. And finally, other colorful ingredients that give a great crunch over a fresh bed of leafy greens with juicy sweet tomatoes were the final touches for this vibrant salad. This is a much more heartier salad than the classic tuna salad.

First, make sure you have your poached eggs ready. Then, make the dressing by combining olive oil, lemon juice, Dijon mustard, red pepper chili flakes, garlic powder, onion powder, salt, and black pepper in a small mason jar.

For the rest of the rainbow tuna salad.
Then, you'll place the tuna and avocado in the middle of the salad bowl, surround it with mixed greens, and top the greens with tomatoes, scallions, purple cabbage, cucumbers, red radishes, and sliced celery. Finally, dress the salad with the vinaigrette and garnish with chopped parsley.

Cut the cabbage into wedges, then lay flat on the cutting board to easily make slices.
Slice the cucumber in half lengthwise first, then thinly slice for half moons.
Slice the red radishes in the same way with the tips removed.
Then, for a beautiful cut, slice the celery on a diagonal.
Cut each Campari tomato into eight pieces by cutting it in half, slicing halves, then halving those.
Finally, line up the scallions and thinly slice them.
For over-riped avocados, mix them into the tuna. But for ripe tomatoes, just dice and place on top of the tuna in the salad bowl.
When poaching the egg, the egg white should cover the egg yolk after placing it in the water that has been swirled to form a funnel.
If the dressing ingredients are placed in a jar to shake, this eliminates the process of using a blender or whisk.

- Mason Jar - A small 4-ounce mason jar makes the salad dressing. I also used the Ball Mini 4 Oz Mason Jars to develop this recipe. Evidently, it's the right size to personalize dressings and prevent waste.
- Mandoline - Even though I did not use my Benriner Japanese Classic Slicer for this recipe if you want to shorten the prepping time, use a slicer for the cabbage, cucumber, radish, and celery.
- Salad Spinner - This can be used to rinse your greens and herbs. For this recipe, I used the Cuisinart Salad Spinner. To learn more tips on this useful tool, check out Cook's Notebook: Salad Spinner post.

- Refrigerator - To store in the fridge, you can place everything together except for the dressing in portioned airtight containers. Or in a large, airtight container with a paper towel on the bottom to soak up any moisture that may ruin the vegetables over time. Store the dressing in its container. The rainbow tuna salad lasts up to three days—the vinaigrette lasts two weeks, for instance.
- Freezer - I do not recommend freezing this salad.
Air Tight Food Containers - I use Glass Food Storage Containers with a plastic clipping lid to store food. For example, I always suggest glass storage containers since you can microwave them and hold food without staining the container, and the glass keeps them at a more stable temperature, which keeps the food fresher longer.
Have all ingredients prepped before assembling the rainbow tuna salad. This will also save you time by preventing running back and forth to grab ingredients.
Frequently Asked Questions
Add one tablespoon of white vinegar to three cups of water in a small pot. Bring the pot of water to a simmer. The water will be suitable to poach an egg when the bottom of the pot has tiny bubbles with no bubbles forming on the surface. If bubbles are starting on the surface, lower the heat. Then, swirl the water to flow in one direction using a spoon or a skimmer.
Poaching one egg at a time, crack the egg on a flat surface and gently drop it into the middle of the water funnel. Then, the egg white should slowly begin to cover the egg yolk. Allow the egg to poach in the water for 4 minutes.
Gently pick up the poached egg and tap for firmness; this will take practice. You want it where you can fill the egg white, which has solidified, but the egg yolk is still liquid. Once it has reached this, remove it from the water. If you are poaching another egg, swirl the water again, then add the egg and continue with the rest of the steps.
