Spread the banana slices over a lined tray or silicone cake pan and freeze until frozen solid.
Make the nice cream
Scoop out the avocado from the skin and cut it into small chunks. Add them, along with the frozen bananas and mint leaves, to a food processor.
Process until smooth.
Add some spinach leaves and process further. Add more, as needed, until you reach the desired color.
If desired, add more mint to increase mintiness.
Once smooth and well combined, open the food processor and add some chocolate chips. Gently fold them into the ice cream.
If the ice cream is solid enough, scoop it into bowls or cones and serve immediately.
If it's slightly too soft, place the ice cream in the freezer for several minutes to harden it before scooping it and serving it.

Notes
Nutritional information has been calculated using a generic chocolate measurement. Using a vegan & paleo chocolate will change the information slightly.Freeze the fruit ahead of time to have it ready to make the ice cream in a matter of minutes when the urge strikes. For a firmer ice cream, you can also freeze the avocado chunks with the banana slices.Instead of chocolate chips, you can also process some chocolate pieces in a food processor to make small bits to add the ice cream.Peppermint extract can be used in place of the mint leaves. (A few drops of mint essential oil is another option. Be sure to use food-grade oils and follow safety instructions. They are not recommended for use with young children.)This ice cream is already quite sweet because of the bananas, but you can further sweeten it with stevia, maple syrup, or another sweetener of choice, if you feel it needs it.
