Preheat the oven to 450 degrees and lower the oven down to 425 degrees if the hash browns are getting too browned.
Line a baking pan (with sides) with unbleached parchment paper.
In a large bowl, toss all of the ingredients together well.
Spread gently and evenly over the parchment paper-lined pan.
Bake for around 30 minutes, until the tops and edges are brown and crispy.
Serve immediately topped with avocado and Cholula sauce.
