Finely dice the tomatoes, cucumbers, and bell peppers, and add to a large salad bowl.
Add the olive oil, salt, feta, and nuts, and stir to combine.
Step 2
Now open and pit the avocados.
Using a butterknife, carve large chunks into the meat of the avocado, and scoop the chunks directly into the salad bowl with a spoon.
Stir to incorporate the avocado (it will break up slightly, adding a creamy element to the salad).
Step 3
Add the lemon juice, stir again to combine, taste, and adjust for seasoning. This salad does not keep well, so simply reduce the amounts if you need less.
