What dishes do you think would be good made with walnut oil?

My cardiologist says I should consume more omega 3 when eating oils. Olive oil is heavy in omega 6, which supposedly is not as good, so I need to replace some of my olive oil intake with something else. I googled and found out walnut oil has omega 3, and that interested me, I figured it would be good in some salads. What other ideas do you have for the walnut oil, and have you ever used walnut oil?

Thanks!
