In a nonstick skillet over medium heat, cook the chorizo for 5–6 minutes until browned and fully cooked. Break it apart into crumbles as it cooks. Remove from the skillet and set aside.
In a bowl, whisk the eggs with heavy cream, salt, and pepper. Using the same skillet, add butter or oil and pour in the eggs. Stir gently until soft-scrambled and fluffy. Remove from heat.
Warm your keto tortillas in a dry skillet or microwave. Spoon eggs and chorizo into each tortilla. Add cheese, avocado, and sour cream on top.
Sprinkle with chopped cilantro and drizzle with your favorite low-carb hot sauce or salsa. Enjoy warm!
