Here's a way to cheat when you want homemade ice cream. Stir pecans, peaches, cookies, and a few other ingredients into purchased vanilla ice cream. With all those extra goodies, every one will think you made the ice cream from scratch.
Slightly soften ice cream. Puree half the peach pieces and the peach nectar in blender. Add ice cream. Pulse 6 to 8 times, until blended.
Pour into 8 x 8 x 2-inch metal pan. Place in freezer while preparing remaining ingredients.
Finely dice remaining peach pieces. Toast pecans in small skillet over medium-high heat, stirring, until lightly browned and fragrant, 3 minutes. Transfer to plate to cool.
Remove pan with ice cream mixture from freezer. Stir in chopped peaches, pecans, cookie pieces, nutmeg and cinnamon until well blended. Freeze until firm, about 6 hours or overnight. Serve in waffle bowls, if desired.
