Bring water to boil in a small covered saucepan.
Place octopus in saucepan, cover and reduce heat to medium-high and cook for 10 minutes. This is a lazy way to steam / boil them.
Remove from heat and drain remaining water using the lid.
Add olive oil, garlic, parsely, oregano and squeeze the lemon over the top and mix together.
Place on pre-heated medium BBQ grill plate and cook around 2 minutes with the head facing down and around 5 minutes with the tentacles facing down.
