Measure out all of the ingredients and chop the vegetables.
Add half the jar of marinated Feta cheese to a large mixing bowl. Add the tablespoon of olive oil and mash the cheese using the back of a fork, stirring as you go. To the cheese and oil, add the dried oregano and a liberal pinch of sea salt.
Add the cucumbers, Kalamata's, red onion, quartered cherry tomatoes, and picante slivers to the cheese mixture. Add 2 or 3 (or to taste) tablespoons of the olive oil from the marinated Feta to the ingredients and mix everything together very well. Taste for seasoning and add additional sea salt or oregano if necessary. Decide if you will require additional olive oil and add from the marinated Feta jar as necessary.
At this stage, and only if using, garnish with additional Kalamata olives, the remaining jar of Feta cubes (left whole), toasted pine nuts, or fresh oregano leaves. Enjoy as a side dish, in a pita, or atop lettuces as a salad.
