The best way to cook tuna fillets is on a very hot grill so that they are seared but not fully cooked through to the center. This is an ideal recipe for a light and healthy lunch.
1 1-inch tuna steak per person
1 tablespoon freshly squeezed lemon juice
Salt to taste
1 teaspoon coriander seeds, coarsely ground
1/4 teaspoon freshly ground black pepper, or to taste
1 teaspoon dry oregano, or a combination
Lemon wedges, and/or extra virgin olive oil, to serve (optional)
1. Drizzle the tuna with lemon on both sides and sprinkle with salt.
2. Mix all the spices together in a bowl. Dip each cut side of the fillets into the spice mixture, so as to cover the surface well.
3. Heat the broiler, the charcoal grill or a griddle, and grill the tuna fillets until seared and firm. Be careful not to overcook.
4. Serve immediately with lemon wedges and drizzle with fresh olive oil, if you like.
