Ingredients
  • 2 6-ounce Tuna steaks
  • 1 large Avocado
  • 1/4 cup Red onion, finely chopped
  • 2 tablespoons Lime juice
  • 2 tablespoons Cilantro, chopped
  • 2 tablespoons Olive oil
  • to taste Salt
  • to taste Black pepper
  • 1/4 teaspoon Chili flakes (optional)

Prepare the Salsa

In a medium bowl, mash the avocado with a fork. Add the red onion, lime juice, cilantro, salt, pepper, and chili flakes (if using). Mix well and set aside. Taste and adjust seasonings as needed.

Prepare the Tuna Steaks

Pat the tuna steaks dry with paper towels. Season generously with salt and pepper.

Sear the Tuna

Heat the olive oil in a large skillet over medium-high heat. Once the oil is hot, carefully place the tuna steaks in the skillet. Sear for 2-3 minutes per side for medium-rare, or longer if you prefer it more well-done. Be careful not to overcook the tuna, as it can become dry.

Serve

Remove the tuna steaks from the skillet and let them rest for a minute or two. Top each tuna steak with a generous spoonful of avocado salsa. Serve immediately. Good options for a keto side dish include asparagus and spinach.
