Preheat the oven to 375ºF. Grease a 9 x 13" baking dish with avocado oil or use parchment paper to line it for easy cleanup.
Cook the chorizo in a large skillet over medium heat until browned and broken into crumbles. Add it to the greased baking dish.
In the same skillet, turn up the heat to medium high and add the potatoes, jalapeño, bell pepper, and onion. Sauté until potatoes are fork tender and lightly browned, about 7-8 minutes. Add to the baking dish and mix with the chorizo.
In a large bowl, whisk the 12 eggs with coconut milk and spices. Pour over the meat and veggies.
Transfer the dish to the oven and bake for 30 to 35 minutes or until golden on top and eggs are set.
Slice into 8 squares and serve! Try a drizzle of hot sauce or ranch over top, and garnish with sliced green onion if you like.
