In the bowl of a food processor, break up the frozen fruit, pulsing occasionally, until it's in small pieces.
Add in the milk, pea protein powder, and nut butter, vanilla & salt if using, and blend until smooth.
You may need to add a little more milk (1-3 more tablespoons) while you keep blending to get it to the consistency of soft serve.
If you want it to be a little firmer and more scoopable, you can pop in the freezer for 5-10 minutes.
Serve as-is or topped with your favorite ice cream toppings!
For a cookie dough ice cream experience, try banana as your base, and then top with chopped DH Chocolate Chip Cookie Dough Bites!
