Cook sausage for about 5-7 minutes until browned. Add the hashbrowns and cook for another 5-6 minutes until crispy.

Whisk eggs with a splash of milk and cook in the open space on the griddle until just set, adding cheese if desired.

Assemble tacos by placing sausage, hashbrowns, and scrambled eggs into each pancake shell. Drizzle with maple syrup.
