Healthy and delicious. Canola oil is relatively flavorless. Using it in the marinade and vinaigrette allows the zingy taste of the Dijon mustard and fresh herbs to come through. Canola oil also provides heart-smart omega-3 fat along with the salmon and walnuts. The marinade doesn’t have a lot of acid, so it’s perfect for marinating the salmon for up to 10 hours before grilling (or broiling). From joyofkosher.com.
