Place pecan halves on baking sheet on parchment paper with butter cut into small pieces.
Put baking sheet in 350 degree oven just until butter melts and then remove.
Toss pecans with butter to coat and then sprinkle with salt. Toss again to coat with salt.
Toast pecans at 350 degrees for 5 minutes and then toss again. Toast additional 3-5 minutes or until fragrant. Remove from oven and cool completely.
Melt chocolate melting wafers according to package directions - usually in 30 second intervals at 50% power, stirring after each interval until melted and smooth.
Drop pecans in chocolate a few at the time, stirring to completely coat and then removing with forceps or needlenose pliers.
Allow excess chocolate to drain off for 2-3 seconds each and then lay flat on clean parchment paper until chocolate is firm and set.
If desired excess chocolate can be trim from around edges of pecan halves with sharp knife.
