Heat 2 tablespoon grapeseed oil and butter in a 4 quart Casserole over medium-high heat. Add shallots and saut? for 2 minutes or until shallots are translucent. Add garlic and the sundried tomato and cook for another minute. Pour in half of the wine and let it reduce for a few minutes.
Add fennel, stir, cover and cook for about 8 minutes or until fennel is tender.
Add the tomato, basil and parsley. Stir well.
Embed the halibut filets in the vegetables, making sure to leave a thin layer of vegetables at the bottom. Season with salt and pepper. Spoon a little of the vegetable mixture over the top so the fish is covered.
Place the lemon slices over the top. Pour the rest of the wine into the pot. Add 3 sprigs of Thyme.
Then put into the oven for 16-18 minutes or until the Halibut flakes with a fork test.
Turn oven to 500 degrees or broiler to low heat.
In a small bowl combine panko, olives, oil and Thyme leaves. Spread evenly the topping mixture over the fish and vegetables and bake or broil for 4 – 5 minutes or until golden brown.
