Peel and dice your potato into small cubes.
Heat the canola oil in a saucepan over medium-low heat.
Add the potatoes and sauté until they are lightly golden and starting to soften.
Open the can of corned beef using the key provided. (Pro tip: Pierce a small hole on top first to release the vacuum pressure and make it easier to open!)
Add the corned beef to the pan, breaking it apart with a spatula. It’s already cooked, so you just want to heat it through.
Stir in the sofrito for that authentic Puerto Rican taste.
Add the tomato sauce and give everything a good mix.
Toss in the drained corn.
Cover the pan and reduce the heat to low.
Let it cook for about 10 minutes, or until the potatoes are tender and all the flavors have melded together.
Serve your corned beef over fluffy white rice and pair it with tostones, maduros, or a fresh avocado slice.
