Preheat oven to 450°. Drizzle olive oil in a large sauté pan set over medium-high heat. Add onions or shallots, and garlic. Sauté 1 minute.
Add fennel and radicchio, sauté 3 minutes. (Reserve some radicchio for garnish.)
Season halibut with salt and pepper. Move fennel and radicchio mixture to side of pan (away from heat) and add halibut. Sear halibut for about three minutes per side. Remove fish from pan and set aside.
Add turmeric and lemon juice to pan and stir. Move fennel and radicchio mixture back to the center of pan, add white wine and stir; simmer for 4 minutes.
Add stock, and place fish back in pan. Put in oven for five minutes to finish cooking. Cooking time will vary depending on the thickness of fish; you may need to add more time for thicker pieces.
Place in shallow bowls and garnish with a drizzle of olive oil and sprinkling of radicchio.
*Fresh turmeric is available at Rainbow Bridge Natural Foods in Ojai; Whole Foods Market in Oxnard and Thousand Oaks; Lassens Natural Foods and Vitamins, multiple locations; and Apna Spiceland in Thousand Oaks.
