  • 2 tablespoons extra virgin olive oil
  • 1 cup medium sweet onion, chopped
  • 1 red bell pepper, chopped
  • 1 small zucchini, sliced
  • 1 cup pineapple, diced
  • 1 tablespoon soy sauce
  • 2 tablespoons lemon juice
  • Salt to taste
  • chopped green onion and cilantro for garnishing
  • 1 cup green onion, roughly chopped
  • 1 clove garlic
  • 1 ounce ginger (about 1 tablespoon minced ginger)
  • 1 serrano pepper, seeded and chopped
  • 1/4 cup packed cilantro
  • 1 teaspoon sea salt

  • 3/4 teaspoon dried thyme

  1. First, make the tuna marinade. Combine green onion, garlic, ginger, serrano pepper, and cilantro in a food chopper or food processor, chop finely, then transfer to a medium bowl; add the rest of the ingredients from the marinade; mix well.

  2. Add tuna chunks into the marinade, combine and coat well. Cover and marinate for 4 hours or overnight.

  3. When ready to cook, add 1/2 cup quinoa and 1 cup water in a small saucepan. Bring to a boil and simmer for 10-15 minutes until the quinoa is tender and fluffy. Set aside.

  4. In the meanwhile, heat up 2 tablespoons extra virgin olive oil a 10-inch cast iron skillet over medium-high heat. Add sweet onion, bell pepper, zucchini and cook for 5 minutes or until the vegetables start getting tender.

  5. Stir in tuna with the marinade and pineapples into the skillet, stir a couple times and then add 1 tablespoon soy sauce and 2 tablespoons lemon juice. Continue cooking for about 5 minutes or until the tuna is cooked through. Taste during cooking and add a dash of salt if desired; stirring often.

  6. Remove from heat; add the quinoa into the skillet; combine well; garnish with chopped green onion and cilantro before serving.
