Salsa, sour cream, avocado, hot sauce, diced onion, and queso frescofor serving (optional)
Instructions
In a large cast iron skillet over medium-high heat, cook the chorizo, stirring frequently and breaking up the meat, until browned and cooked through, 6 to 8 minutes.
Use a slotted spoon to scoop the meat into a bowl, leaving the fat behind in the skillet. You should have at least 1 tablespoon of oil in the skillet. If not, drizzle in a little extra vegetable or olive oil.
Add the potatoes and red onion to the fat in the skillet and cook, stirring frequently, until the potatoes are tender, about 15 minutes.
Stir the chorizo back into the potato mixture and cook until warmed through, 1 to 2 minutes. Season to taste with salt and pepper.
Serve on warm tortillas with your favorite toppings.
Notes
Size matters--Take the time to dice the potatoes very small (¼-inch) and evenly. Potatoes that are cut too large will take a long time to cook.
Add oil if needed--If the skillet seems dry while you are cooking the potatoes, drizzle in a couple teaspoons of vegetable or olive oil.
Warming the tortillas--Wrap your tortillas in foil and warm them on the edge of the fire grate or in the oven while the potato and chorizo mixture is cooking.
