Chop the Tentacles into small pieces.
In a small frying pan add a bit of olive oil and fry tentacles, garlic, onion for about 10 minutes and then set aside to cool off.
Once the tentacles have cooled off add rice, feta, egg, dill, salt and pepper and mix. (you can add fresh tomatoes into the mix to give it a bit of a sweet taste and color)
Add 2 tablespoons of Olive Oil.
Take one Calamari tube at a time and start to stuff with the mix, but be sure not to stuff all of it, leave some room towards the end so that you can sew/close off the opening with a toothpick. Once done with the stuffing take a toothpick and close off the opening of the Calamari.
Pour the remaining olive oil and wine over the Calamari and bake for 1 hour or until golden brown.
