Warm bread in a 350 degrees F preheated oven for 5 minutes.
Slice the bread in half: sprinkle both sides lightly with salt, oregano and drizzle generously with olive oil.
Distribute the anchovies on the bread.
Top with sliced cheese and tomatoes. Sprinkle a little extra salt on the tomatoes.
Cover with the top slice of bread and serve.

The entire pagnotta will make 6 servings.Substitutions and Variations;-Use fresh crust bread such as durum semolina bread; pagnotta or ciabatta. -Other vegetable options include as sun dried tomatoes; grilled eggplant; roasted peppers; olives and capers. -Possible cheese options: caciocavallo; Primo Sale; tuma; provolone; ricotta salata or fresh mozzarella. -Add tuna instead of anchovies.To serve:-Best enjoyed immediately while the bread is still warm or pack along for picnics or a day at the beach.
