Frozen Chocolaty Banana Slices

This is by far the easiest and one of the most delicious ice-cream alternatives in the summer (or any season for that matter), makes 4 sliced bananas:
-------------------
4 bananas-pealed, sliced on a diagonal into 1/2 inch ovals
12 oz walnuts
12 oz bittersweet chocolate (Scharffen Berger makes a great one)
1 T Grand Marnier
Optional-1 t cinnamon
-------------------
1. Lay bananas on a parchment paper lined baking sheet, in one layer; place into the freezer and freeze for one hour.
2. Place walnuts into a blender and grind until fine; transfer into a wide bowl.
3. After the bananas have frozen, using a double boiler, melt the chocolate over medium-low heat, stirring constantly; add Grand Marnier and mix well (add optional cinnamon here).
4. Working in thirds, take the bananas out of the freezer; quickly dip each piece into the chocolate, then into the ground nuts; place dipped bananas back onto the parchment paper and back into the freezer. Wait 15-20 minutes and enjoy!
