Healthy Meal: Grilled Tuna with Basil Butter and Fresh Tomato Sauce

I'm new to the fish fad, but this tuna dish has helped me see the light. This is straight from the Cooking Light recipe box, so you know it's both healthy and delicious. Admittedly, this is neither a cheap, nor easy recipe, but the effort is certainly worth it.

Basil Butter:

• 3/4 cup basil leaves
• 2 Tbs butter, softened
• 1 Tbs fresh lemon juice
  
• 1/4 tsp salt
• 3 minced garlic cloves

Tomato Sauce:

• 2 tsp olive oil
• 1/2 cup finely chopped red onion
• 2 minced garlic cloves
• 3 cups of cherry/grape tomatoes, halved
• 1/2 cup dry white wine
• 3 Tbs capers
• 2 Tbs balsamic vinegar
• 1/4 tsp sugar
• 1/4 cup chopped parsley (I skipped this, but feel free to add)

Tuna:

• 4 6 oz tuna steaks
• 1/2 tsp salt
• 1/4 tsp pepper
• Cooking spray

You get to use your grill pan for this recipe, so here goes:

"To prepare basil butter, combine first 5 ingredients in a food processor; process until smooth, scraping sides as needed. Set aside.

To prepare sauce, heat oil in a saucepan over medium-high heat. Add onion and 2 garlic cloves; sauté 3 minutes. Add tomatoes; sauté 2 minutes. Stir in wine, capers, vinegar, and sugar; bring to a boil. Reduce heat; simmer 5 minutes, stirring occasionally. Stir in parsley. Set aside.

To prepare tuna, sprinkle tuna with 1/2 teaspoon salt and pepper. Place tuna on grill rack or broiler pan coated with cooking spray. Cook 5 minutes on each side or until desired degree of doneness. Serve with sauce and basil butter. Garnish with basil leaves, if desired." (from Cooking Light link above)

I served this with a side of white rice and steamed broccoli:
