In a wide, shallow bowl, gently combine the tomatoes, cucumber, red onion and olives. Keep everything rustic and chunky.
Sprinkle lightly with kosher salt and dried oregano.
Drizzle generously with Fancy Peasant olive oil, then hit it with the vinegar for brightness.
Lay the slab of feta right on top and add one more small drizzle of olive oil over the cheese.
No tossing needed — let diners break up the feta as they serve.
