Not a typically Italian preparation given my ingredients list but I’ll share it here anyway as it’s ridiculously tasty.
Olive oil, a pat of butter, and minced garlic in a stainless skillet. Warm it up and toss in the ahi tuna fillets and warm them up. Sprinkle of salt, ground black pepper, and a splash of teriyaki. Wet the butter and oil with a few ounces of sherry. Flip the tuna to cook evenly and add a few capers and a pinch of red curry paste for some spice. When it’s ready to serve toss in the spinach and wilt it, and serve.
