Chinese five-spice powder gives these grilled tuna steaks an Asian flair. Carrots and green beans sauteed in garlic round out the meal.
1. In a shallow dish, mix together soy sauce, Chinese five spice and pepper flakes. Add tuna, turning to coat. Marinate, covered, in refrigerator for 1 hour.
2. Grill or broil tuna steaks on high for 3 to 4 minutes per side for medium, reserving marinade. Set aside; keep warm.
3. Meanwhile, heat oil in a large nonstick skillet. Add carrots and cook, stirring occasionally, for 5 minutes. Add green beans and garlic and cook, stirring occasionally, for 5 minutes. Stir in reserved marinade and cook an additional 2 minutes. Add nuts.
4. Serve tuna over vegetables. Serve lemon on the side.
