The tuna steaks can be done over direct high heat on an outdoor grill as well.  Serve with new potatoes or over couscous.

Basil-Grilled Tuna With Bitter Greens (Serves 4)

2 cloves garlic
12 basil leaves
2 lemons
Kosher salt
Freshly ground black pepper
1 1/2 tablespoons extra-virgin olive oil
680g fresh tuna (2 or 3 pieces)
1 bunch dandelion greens 
1 head radicchio 
2 Belgian endive

Combine the garlic and basil in a mini food processor or chop up/prep for a mortar and pestle. 
Cut 1 lemon in half and squeeze 3 tablespoons of its juice over them. 
Add a pinch each of salt and pepper, then 1 1/2 teaspoons of the oil. 
Grind or pound to a finely chopped consistency.
Trim any blood spots or sinew from the tuna, then cut the flesh horizontally into 4 steaks of equal thickness, arranging them in a shallow baking dish as you work.
Spread the garlic mixture evenly over each piece of tuna. Marinate at room temperature for 20 minutes, turning the fish over a few times to coat evenly.
Meanwhile, cut the dandelion leaves away from the stems. 
Discard any wilted exterior leaves of radicchio, then cut the head first into quarters and then into thin slices. 
Cut the Belgian endive crosswise into thin slices, coring it and discarding its outer leaves, as needed. 
Combine in a mixing bowl, then add the remaining tablespoon of oil and a small pinch each of salt and pepper. Do not toss yet.
Preheat a grill pan over high heat. Once it's quite hot, transfer the tuna steaks to the pan; cook for 1 to 2 minutes on each side (medium-rare), basting with marinade from the baking dish, until grill marks form. Transfer to a platter.
Toss the bitter greens to coat with their dressing, then arrange the salad around or atop the tuna steaks.
Cut the remaining lemon into wedges or slices and place around the platter. Serve warm or at room temperature.
