Moka pot - adding nutty flavor to coffee

I used a spice/coffee grinder to grind coffee beans for the Moka pot since nothing else was available and the flax seed residue from previous grind left a nutty flavor per chance. I liked the taste and I am now blending beans & seeds together. Does anybody else do the same?? Any advice? Any other ideas how to add a nutty flavor to Moka Pot? Does it add any nutritional value, at all? Thanks!
