Mint chocolate frozen dessert

A simple, soothing, and visually impressive dessert (or breakfast).

Ingredients
3 medium frozen bananas (about 2 cups)
1/4 cup baby spinach greens
1/4t mint extract
2T agave nectar, 3T maple syrup, or stevia to taste
20g mint chocolate (I use a fairly traded bar)

Optional: 1t maca powder; trade the bar chocolate for chocolate chips if you prefer.

Instructions
Chop the chocolate. Blend the bananas, spinach, mint extract, and sweetener until smooth. Add 3/4 of the chocolate to the bananas and stir to combine. Spoon out, garnish with the remaining chocolate, and serve.
