1. In a large bowl, cover the feta with water and let stand at room temperature for 30 minutes to temper the saltiness. Drain and coarsely crumble the feta. Transfer to a food processor and puree. Add the cream cheese, heavy cream, 2 tablespoons of the olive oil and 1 tablespoon of the lemon juice and process until smooth and airy. Refrigerate for 1 hour or up to 2 days.
2. Meanwhile, in a bowl, toss the cucumbers with the remaining 2 tablespoons of olive oil and 1 tablespoon of lemon juice. Add the oregano and season with salt and pepper. Cover and refrigerate for 1 hour or up to 2 days.
3. Serve the whipped feta lightly chilled or at room temperature with the cucumbers and pita toasts – I brush mine with olive oil and sprinkle with salt and pepper before toasting. I also added freshly sliced proscuitto.
Note – I like the diced cucumbers, but you can also slice cucumber and other veggies to use in lieu of pita.
