There is only a little to this except just some beautiful assembly and arranging.
Start by making a batch of my everyday dressing - heavy on the dill! (linked above in the ingredient list)
Open and drain your tuna, pour a tbsp of the dressing into each can, and let it marinate while you assemble the salad.
The first step is to prep everything: wash and dry the lettuce, blanch the green beans, boil and strain the potatoes, hard boil the eggs, halve the tomatoes, thinly mandolin slice the cucumber + onion, strain the kalamata olives and give them a rough chop, slice the caper berries in half, de-pit and slice the avocado, coarse chop the dill.
Once everything is fully prepped it makes it easier to imagine what the larger salad will look like -- Now assemble!
I love separating everything into its little sections, but you can layer it and have fun - use your heart and make it pretty!!!
