I have 2 big pecan trees in my garden, which supply endless amounts of pecans. So I have a similar "problem". And although pecans can stay tasty when stored in a dry place, they do loose their taste over time (~ after a year, although they're still good for cooking).
Basically, what I like to do with my pecans is just eat them raw (without toasting, without salt, without sugar, just open them up one by one and eat them). Fresh pecans don't need any additions as they taste incredible when fresh.
The fact that you have to peel them one by one, slows down the pace of eating, so by the time you've eaten 6-7 you're pretty full and tired of peeling :)
Also, I just bring a bag of them to work and watch my colleagues enjoy pecans. It's actually became similar to a "water cooler effect" where everybody just hangs around the pecans, eating them and talking while taking a break. Which is much better than eating waffles as we normally do when pecans are not around.
