In many countries salmon roe or Keta is not as expensive as conventional caviar.  In the markets at Parthenay, a little village in France where I used to live, which are held every Wednesday, you will commonly buy Keta by the gram at any of the fish stands.  All fish roes contain Omega-3 and you could be getting nearly 2% of your daily intake from every ounce.  With the fresh chives providing 14.65% of your daily antioxidants, this is a match made in brain food heaven. 

Just a word about Pumpernickle bread.  It is one of the least processed of all breads and therefore takes longer for your body to digest.  This is a good thing since it will then provide you with carbohydrates over a long period of time and you'll be less hungry later.  This also qualifies pumpernickle to be lower on the Glycemic index scale with a score of 41 compared to white breads which hover around 68.
