Char-Grilled Tuna With Toasted Corn Vinaigrette And Avocado Salad

This dish was delish. Yum, healthy blah blah BUT the prep time is around 40 minutes. For a relatively simple dish, I thought REALLY?  Perhaps this is obvious if you read through the recipe but as I so often do I skimmed and was frustrated at how long it took to chop everything up. Perhaps I was just cranky last night when I was making it so I am being unfair? You be the judge.  

The tuna:

• 2 teaspoons grated lemon rind
• 1 tablespoon chopped rosemary
• 2 tablespoons chopped basil
• 2 cloves garlic, peeled and minced
• 1 teaspoon finely chopped ginger
• 2 tuna steaks cut into 5cm cubes
• 1/2 teaspoon salt
• Freshly ground pepper to taste
• 2 tablespoons olive oil

The vinaigrette:

• 1/2 cup olive oil
• 1/2 cup fresh corn kernels
• 1/3 cup minced red onion
• 1/3 cup chopped scallions
• 3/4 teaspoon finely chopped fresh ginger
• 1 small clove garlic, peeled and minced
• 2 tablespoons balsamic vinegar
• 2 tablespoons fresh orange juice
• 3/4 teaspoon chopped thyme
• 1 1/2 teaspoons chopped basil
• 3/4 teaspoon chopped cilantro, plus a few whole leaves for garnish
• Salt and freshly ground pepper to taste

Serve with black beans (I found these fabulous canned ones that Norton St Grocer imports. Any Spanish/Latin looking canned black beans will do.

The salad:

• 4 cups mixed salad greens
• 2 avocados, peeled, halved, pitted and each half sliced in half lengthwise

I know the photo is off centre as is the food!
1. To make the tuna, combine the lemon rind, rosemary, basil, garlic and ginger in a large bowl and toss with the tuna. Let marinate at least 1 hour. Heat a grill, preferably using hard wood.  
2. To make the vinaigrette, heat 2 tablespoons of the olive oil in a medium-size cast-iron skillet. Add the corn and cook until brown. Add the red onion and scallions and cook until translucent. Add the ginger and garlic and cook for 3 minutes. Stir in the vinegar and orange juice and remove from heat. Slowly stir in the remaining olive oil and the herbs. Season with salt and pepper. Let stand at room temperature.
3. To make the salad, divide the greens among 4 plates. Cut each piece of avocado lengthwise into thirds, leaving the narrow ends intact. Fanning out the slices, lean 2 slices against the outside of each salad.
4. Heat up the black beans on the stove or in the microwave.
5. When the grill is hot, season the tuna on both sides with the salt and pepper and brush with olive oil. Place on the grill and cook until tuna is charred on the outside and medium in the center, about 3 to 4 minutes per side. Remove from heat and slice each piece into quarters. Put a big ladleful of black beans on the plate. Drape 4 slices of tuna across the top of each salad. Spoon the vinaigrette over the top, garnish with cilantro leaves and serve immediately.
