Start by scoring plantain peels lengthwise with a knife, and then removing the peels. Grate the plantain with a hand grater and set aside.
Place avocado chunks in a bowl and add onion, garlic powder and a pinch of salt and pepper. Mix together well, slightly smashing the avocado. Set aside.
Heat a medium skillet over medium heat for the sausage. Form sausage into 2 patties if using ground sausage. Add sausage to the pan to cook for about 8 minutes, flipping halfway to ensure both sides are cooked.
After the sausage is started, heat another medium pan over medium heat and add the avocado oil. Once hot, add in the grated plantain, forming it into two small separate "hash brown" like patties. Cook for about 3-4 minutes on one side, until the plantains have developed a golden brown crust and slide around easily in the pan. Then, flip the plantains to cook on the other side for 3-4 more minutes.
When the sausage and plantains are almost cooked, heat up another pan to fry your eggs. We like them over easy, but you can prepare them any way you'd like.
Now, make your stacks. Start with a plantain hash brown base and add some of the avocado mixture, then layer the sausage next. Top everything with an egg. Serve and enjoy.
