Chef Donald demonstrates in this video how to make grilled tuna steaks topped with red pepper sauce. The tuna steaks are marinated with pepper and extra virgin olive oil. He avoids salt as it draws out moisture and adds it later. The steaks are cooked on a hot frying pan. For the pepper sauce, he blends the roasted bell peppers in a food processor to a smooth pulp. The pulp is transferred to a sauce pot and heated for about 2 minutes with a little bit of butter and lemon juice. Olive oil or margarine can be added instead of butter. Pour the sauce over the tuna steaks and your dish is ready to be eaten.
