Teriyaki Tuna with Spaghetti

1.In a small bowl, mix together the ingredients for the marinade: soy sauce, mirin, brown sugar, grated ginger, and minced garlic.

2.Place the tuna steaks in a shallow dish and pour the marinade over them. Let them marinate for at least 30 minutes.

3.Cook the spaghetti according to the package instructions. Drain and set aside.

4.Heat olive oil in a pan over medium heat. Add minced garlic and sauté for a minute until fragrant.

5.Add the cooked spaghetti to the pan and toss to coat with the garlic-infused oil. Set aside.

6.In the same pan, heat vegetable oil over medium-high heat. Add sliced onion and julienned carrot. Stir-fry for about 3-4 minutes until the vegetables are tender-crisp.

7.In a small bowl, whisk together the ingredients for the teriyaki sauce: soy sauce, mirin, brown sugar, water, and cornstarch. Pour the sauce into the pan with the vegetables and cook for a minute until the sauce thickens.

8.Remove the tuna steaks from the marinade and season with salt and black pepper.

9.Preheat a grill pan or grill over high heat. Grill the tuna steaks for about 2-3 minutes per side until cooked to desired doneness.

10.Serve the teriyaki-marinated tuna over the garlic spaghetti and stir-fry vegetables. Garnish with sesame seeds and sliced green onions.
