Preheat oven to 425. Line a large baking sheet with parchment paper. Place all of the diced potatoes, onions, and peppers into a large bowl. Add the avocado oil and melted ghee.
Mix the spices in a separate small bowl, then pour over the potato/onion/pepper mixture. Use your hands to mix them well. Dump the contents of the bowl onto the sheet pan.
Bake for 25 minutes, stirring once. Turn the oven temperature up to 475 and cook for an additional 10 minutes, until crispy. Serve topped with eggs or however you would like! Enjoy!
