If I was doing the Mediterranean diet, I'd be eating aglio e olio every other day, with a protein (probably grill steak or chicken) for lunch/dinner. I don't eat seafood, but if you like seafood, switch out the steak/chicken with fish like salmon or shrimp.
I'd also only eat bread I made myself, since processed bread is a no-no. Just make a basic bread dough (flour/water/salt/yeast), let it rise, punch it down, shape it into rolls, let them rise, then bake. Serve with olive oil and minced garlic with some red pepper flakes as a dipping sauce.
As someone who has family in Italy, the key to the health of Italians is the fact that they're physically active. After you eat a meal, go outside and walk around for 10 minutes, get the blood flowing. Italians pretty much walk everywhere.
