Seared Tuna With Citrus Sauce - cooking recipe

Ingredients

1 1/2 lbs tuna steaks, about 6 oz each
2 tablespoons olive oil
8 ounces fresh arugula (or more)
4 tablespoons soy sauce
3 tablespoons orange juice
1 tablespoon lemon juice
1 orange, zest of, grated
1 lemon zest, only grated
3 garlic cloves, peeled and crushed
1 1/2 inches fresh ginger, grated
2 oranges, in segments (remove white pith)
3 teaspoons sugar
1 inch dried chilies, crumbled or 1 small chili pepper, chopped, seeds removed
salt

Preparation

Mix together the ingredients from the soy sauce down to the chilli pepper, stir well, and stand for a while for flavours to mix.
Put in a suitable container in a warming oven to just warm through.
Brush the tuna steaks with the olive oil and just sear quickly on both sides in a hot griddle pan over very high heat for rare meat -- or cook to your liking. Use salt to taste.
Arrange the arugula on 4 plates, top each with a tuna steak, and drizzle the citrus sauce with orange segments over each serving.
Serve immediately -- but can be served cold.
