Steam-fry the potatoes

• Heat the oil in a frying pan and add the diced potatoes.
• Cover and let them steam-fry, stirring occasionally, until lightly charred on the outside.

Add chorizo and onion

• Drop the crumbled chorizo into the pan with the potatoes.
• Add the diced onion and stir everything together.

Add the chiles

• Stir in the chopped jalapeño and serrano.
• Toss everything so it cooks evenly.

Add tomatoes and seasoning

• Once the potatoes break easily with a silicone spatula, add the diced tomatoes.
• Season with salt, pepper and garlic powder, then stir well.

Finish and serve

• Cover the pan and turn off the heat so the potatoes keep a slight fried texture.
• Serve hot with salsa.
