Ingredients

Scale
  • 1 lb Breakfast Sausage (substitute with turkey sausage or vegetarian options)
  • 6 large Eggs, beaten until smooth
  • 1 cup Milk (plant-based milk can be used for a lighter version)
  • 2 cups Bisquick Mix (other pancake or biscuit mixes may be used)

Notes

  • Store leftovers in an airtight container in the fridge for up to 3 days.
