Mix 100g of thick Greek yogurt, 2 spoons of allulose, and 2 spoons of lemon juice together to make a yogurt ice cream base.
Put the mixture into a piping bag, pipe it nicely into a container, and freeze for 1 hour.
Melt dark chocolate in the microwave for 30 seconds, pour over the yogurt, and optionally, sprinkle crushed macadamia nuts on top.
Top with sugar-free protein cereal and frozen strawberries to finish.
