Heat a cast iron skillet over medium high heat and add the avocado oil. Once heated, add the sweet potatoes and onions. Saute for about 5-10 minutes until the sweet potatoes begin to soften. Add a pinch of salt and pepper.
Add the peppers and cook for another 5 minutes, stirring frequently. Once the potatoes are cooked through, push the potato and vegetable mixture to the side of the pan and add the chorizo and cook until cooked through - about 5 minutes.
Once the chorizo is cooked mix the sweet potato mixture with the chorizo until combined. Make four small wells in the mixture for the eggs.
Crack an egg into each well, cover, and allow the eggs to cook for about 5-10 minutes until you reach desired doneness of the eggs.
Remove from the heat and garnish with fresh parsley or cilantro if desired.
