½14oz can diced tomatoes
Pinch sugar
1 tspnchopped fresh thyme leaves
Palmfulslivered fresh basil leaves
Instructions
Heat 2 tbsp olive oil and butter in a large, heavy skillet over medium heat and sear skinned halibut steaks for 3 minutes each side ( thicker steaks may need longer so cook until fillets start flaking) . Set aside and loosely cover with foil to keep warm.
In the same skillet add the rest of the olive oil and add the onion. Cook, stirring often until tender - about three to five minutes then add the mashed garlic and the capers. Give them a quick stir to release the flavors.
Add the tomatoes, salt, pepper and a pinch of sugar. Stir in the thyme, bring to a simmer and cook, stirring often, for 15 to 20 minutes, until the sauce is thick and fragrant. Taste and adjust seasonings. Add the fish back to the sauce and heat for a minute each side the add half the shredded basil and stir for a further minute.
Place a spoonful of sauce on each plate, and place a piece of fish partially on top. Garnish with the rest of the basil leaves and serve.
