To a large, microwave-safe bowl, add the pecans, rice squares cereal and pretzels. To a small microwave-safe bowl, add the butter, brown sugar, maple syrup, salt, & nutmeg. Microwave the butter mixture 1-2 minutes, until melted, then pour over the dry mix. Toss well to combine.
Microwave the snack mix in 45-second intervals, about 4-5 intervals total, until the mix is fragrant, golden, & toasty. If you prefer to use your oven, toast at 250 degrees F for 1 hour, tossing the mix every 15 minutes.
Cool the mix completely, then stir in the cranberries & dark chocolate chips. Enjoy!
