Create a refreshing and healthy salad by incorporating soy sauce-marinated fish. Start by marinating the fish in a mixture of soy sauce, lemon juice, garlic, and a touch of olive oil. Let it sit for at least 15 minutes. Grill or pan-fry the fish until cooked through. In a large bowl, combine mixed greens, cherry tomatoes, cucumber slices, and any other vegetables you like. Top the salad with the cooked fish and drizzle with a soy sauce-based dressing. Enjoy a light and flavorful meal.
