To make delicious grilled tuna steaks, you need the perfect ingredients. Here’s a simple list:

Main Ingredients

  • Tuna Steaks: Fresh or frozen, about 1-inch thick.

Marinade Ingredients

  • Coconut Aminos (or Soy Sauce)
  • Sesame Oil (or Olive Oil)
  • Garlic, minced
  • Ginger, minced
  • Honey (or Maple Syrup)
  • Salt, to taste
  • Black Pepper, freshly ground
  • Red Pepper Flakes (optional, for heat)

For Grilling

  • Neutral Oil (like canola or vegetable oil) for brushing
