What to do:
1. Remove the soft part from the inside of both pieces of
the bread, then rub butter inside the holes.
2. In a cup, mix the oil and vinegar together. Tear the
lettuce into small pieces, and sprinkle the oil and vinger
over them.
3. Place the lettuce in one piece of the bread, with olives
and tomatoes. Sprinkle with a bit of salt, pepper, and/or
oregano.
4. Place the ham, cheese, and turkey on top of the olives
and tomatoes. Cover with the other half of the bread.
