Preheat the oven to 350 degrees F.
Heat the olive oil in a medium saucepan over medium-low heat. Add the onions and cook until nearly translucent, about 5 minutes. Add the Greek Seasoning, oregano and tomatoes, and season with sea salt. Simmer until the sauce thickens slightly, about 15 minutes. Stir in the parsley and shrimp.
Transfer the shrimp mixture to a small baking dish. Top with the feta. Bake until the shrimp are cooked through, about 25 minutes. Add more Greek Seasoning and sea salt if desired. Garnish with the olives. Serve hot, with the crusty bread for dipping.
