1 lb fresh asparagus, cut into 1" pieces
1 lb halibut or other lean fish steak, cut into 1" pieces
1 medium onion, thinly sliced
3 cloves garlic, finely chopped
1 tsp ginger
1 cup sliced mushrooms
2 Tbsp reduced-sodium soy sauce
1 Tbsp lemon juice
1 medium tomato, cut into thin wedges
Spray 10" nonstick skillet with nonstick cooking spray. Heat over medium-high heat.
Stir-fry asparagus for 2 minutes, then add fish, onion, garlic, and ginger. Stir fry 2-3 minutes or until fish almost flakes with a fork.
Carefully stir in the remaining ingredients and cook until heated through and fish flakes easily with a fork.
Serve with additional soy sauce if desired.
