Triglie are what Americans call Red Mullet, rouget in French, and are most commonly found in Triglie alla Livornese, a simple dish that includes tomato sauce with garlic, parsley, olive oil and red pepper flakes.
Triglie Alla Calabrese adds capers, oregano and olives.
The Triglie here are roasted on top of lemon leaves, an even simpler preparation that is quite colorful.
