Preheat oven to 180 degrees Celsius.
Grease 6 small round baking cups and place with baking paper, but in a way so the paper comes out of the cup.
Add to the food processor eggs, lemon rind, ricotta, sharp cheese, oregano, olives, season with salt and pepper, and blend.
Pour the mixture into the cups and bake for 35 minutes, until the tops became golden.
Then take them out from the oven and let them cool. Then turn them upside down and take them from the cups and remove the baking paper.
You can serve them by itself or with green bean stew.
