If you’re looking for a meaty protein, but want to steer clear of steak, try tuna steaks! While I always push salmon, tuna is also rich in Omega-3 fatty acids that are thought to improve brain function and mood. Omega-3s in tuna also make it a natural anti-inflammatory. Living with post concussion syndrome (PCS), these are elements all of our brains can use more of!

Whether your hosting a dinner party or just looking to switch up the weekly menu, try this fancy, yet incredibly easy recipe featuring tuna steaks with a bold avocado-parsley, lemon sauce! Both your guests, and your brain will be impressed. Bon Appetit!

Tuna with Avocado-Parsley-Lemon Salsa

Course: Main Dish
Cuisine: Seafood
Servings: 4


  • 2 tbsp lemon juice
  • 1 tbsp capers
  • 1 clove garlic optional
  • 1/2 cup flat leaf parsley leaves
  • 2 tbsp extra virgin olive oil
  • 1/4 tsp kosher salt
  • 1 avocado diced
  • 1 lb tuna steak 3/4 inches thick
  • 1 tsp coarsely ground black pepper


  • Make the salsa: Blend 1 Tbs of water with the lemon juice, capers, garlic, parsley, oil, and salt in a small food processor or blender until a sauce forms. In a bowl, toss the sauce with the avocado.
  • Season the tuna with the pepper and grill on a clean, oiled grate over medium-high heat until marked, about 2 minutes. Lift and pivot the tuna 90 degrees and grill for another 2 minutes on the same side. Turn the fish over and cook to desired temperature, another 3-5 minutes for medium. Serve with the salsa.
