Summer! Summer! Summer: Greek Salad

We've been to Greece just once, in September 2001, and since then we would love to go back and have an extensive tour of all the islands. For which we would need more then three weeks, so we keep postponing it!!!
But just to remind us how beautiful Greece is we make often, especially during summer month, what we European call Greek salad. If you can find very good and fresh ingredients it will be a must on you table too!
Of course I thought: why not make verrines out of it??? You can always make a verrine, remember!!! Verrines are our friends!

Cucumber, peeled and diced
Red pepper, diced
Spring onion, minced
Cherry tomatoes, halved
Feta cheese, diced
Black olives
Oregano
Extra-virgin olive oil

In your glasses, layer the ingredients in the order you prefer (I gave you the ingredients in the order I used them). Dress with dry or fresh oregano and drops of extra-virgin olive oil.
Serve it right away.
