I love serving Tuna Steaks up with these tasty side dishes: Crispy Garlic Broccoli, Pan Seared Bok Choy, Instant Pot Steamed Rice, Asian Cucumber Salad or Sautéed Spinach and Garlic. I'm also a sucker for serving it up with a tasty sauce for dipping such as 3 ingredient Spicy Mayonnaise or Japanese Style Roasted Sesame Dressing.
