Cut the squid into small squares.
Cut the octopus legs into slices.
Heat up a splash of oil in a skillet, along with some butter.
When it's nice and hot, add the onion, bell pepper and garlic.
Sauté for 2 minutes or until tender.
Add the squid and cook for 30 seconds.
Squeeze the juice from 2 lemon wedges into the skillet.
Add the oregano or parsley and grind in some salt and black pepper.
Add the octopus and cook for 30 seconds, stirring all the time.
Taste a piece of squid to see if it's tender.
Don't overcook the squid - it will only take about a minute in total to cook.
Serve with the remaining 2 lemon wedges.
