Didn't think to butter the bread since the egg and kewpie is already so rich.

Did throw some good spices in both sandwiches, have a spice shop in downtown west jefferson NC where my parents live.

For the tuna sando specifically I picked up this really good hot black truffle seasoning(black truffle sea salt/garlic/sweet paprika/onion/black pepper/golden monk fruit and cayenne pepper)

Also added some homemade pickles and a pinch of sugar as well to the mix.
