Nut Oils

Walnut and grape seed oils are lighter in flavour and perfect for dressing salads. It is rich in omega-3 fatty acid ALA and other unsaturated fatty acids, as well as ellagitannins and other polyphenol compounds that act as antioxidants. Thus, consuming walnut oil may improve blood sugar levels and boost heart health.

A delightful lentil salad can be made with walnut oil:
Add lentils, garlic, onion, carrot, and water in a large saucepan.
Bring to a boil. Add salt to taste and reduce the heat to low.
Cover and simmer 35 to 45 minutes until the lentils are tender. 
Drain through a strainer set over a bowl.
Whisk together the vinegar, Dijon mustard, salt, and shallot or garlic. 
Whisk in the oil and 2 to 4 tablespoons of the liquid from the lentils. Stir into the lentils.
