Toast the walnuts: Place walnuts in a dry skillet. Set stovetop to medium heat and let nuts cook, stirring occasionally, until fragrant and lightly toasted, about 10 minutes total. Remove toasted walnuts to a bowl to cool down (leaving them in the pan will cause them to continue cooking). Chop nuts once cool, if desired.

To assemble: For each bowl, start with ½ cup Greek yogurt. Top yogurt with 2 tablespoons each banana chips and walnuts. Sprinkle with chocolate chunks and a drizzle of honey. Enjoy!
