Whisk together egg white, brown sugar, cocoa powder, vanilla extract, and salt until well blended. Add about 1 tablespoon water to thin mixture slightly. Fold in pecan halves until well coated. Spread mixture onto parchment lined baking sheet.
Bake at 325 degrees F. for about 15 to 20 minutes or until mixture well set. Stir pecan mixture several times during baking. Allow pecans to cool completely and transfer to a bowl. Mix in dried cherries, pretzels, and yogurt covered raisins.
