In one bowl, mash up sweet potato kugels together.
In another bowl, mix plain Greek yogurt (I used Chobani), honey, and cinnamon.
Scoop about 1/4 of the potato mixture into a glass. Layer on 1/4 of the yogurt mixture, sprinkle with graham crackers and walnuts. Repeat another layer of each and top with more nuts and cinnamon. Repeat in another glass.
That’s it! This parfait is smooth yet crunch, really filling, slightly sweet, and chock full of vitamins. Win!
