1 tablespoon chili-lime seasoning (such as Tajin®)
Preheat the oven to 250 degrees F (120 degrees C). Line a baking sheet with parchment paper.
Place nuts into a medium bowl. Mix butter and chili-lime seasoning together in a small bowl; pour over nuts and toss until evenly coated. Transfer to the prepared baking sheet and spread out into a single layer.
Bake in the preheated oven until nuts are lightly browned, 18 to 20 minutes, stirring every 6 to 7 minutes. Remove from the oven and place nuts on a paper towel-lined plate. Let cool completely before serving or storing.
