Two 6-8 oz halibut fillets 1/2 c diced onion 1/4 c diced carrot 1/4 c diced celery 2 garlic cloves, minced Olive oil 1 c cooked, drained, and chopped spinach Saute the onion, carrot, garlic, and celery in 2TB olive oil for about 5 minutes. Squeeze as much liquid as possible out of the spinach and add to pan. Saute for another minute, stirring, and season to taste with S&P. Season the fish with S&P and rub with olive oil. Place in a shallow baking dish and spread 1/2 the vegetable mixture over each. Bake at 400f until done, about 10 minutes.
