If needed, dice up the strawberries and peach. No need to peel the peach.
Add the diced strawberries, diced peach, honey, and juice from half a lemon to a blender. Blend until smooth. Pour into the Ninja Creami container.
Freeze on a level surface for at least 24 hours.
Remove from the freezer and process on the SORBET setting. Add a splash of water and respin if needed. (Mine just needed one respin).
Notes
If you want your sorbet a little sweeter, add three tablespoons of honey instead of two.
If you want to use frozen fruit, you can, but I suggest letting it thaw a bit so it is easier to blend, otherwise your blender will have a hard time, since there is so little liquid being added. Fresh fruit should blend pretty easily.
If you have leftovers, smooth out the top and return to the freezer. You may need to reprocess before enjoying again or leave on the counter for a bit to thaw before the sorbet is scoopable.
