Pour vegetable oil into a large frying pan, over medium-high heat.
When hot, add minced beef, stir until browned.
Add sofrito, crushed garlic, stir and cook.
Mix tomato paste with 2 tablespoons water and add to the meat, add seasoning cubes, salt, chilli and potato, stir and cover, lower heat to a simmer.
Cook until the potato is soft, taste and correct seasoning.
If using as a stuffing e.g for empanadas, be sure your filling is moist but not soggy, if it is soggy, leave it open and crank up the heat to dry out.
To serve as a side e.g to rice, it needs to have a little liquid in it.
Add to scrambled egg or use to fill tortilla wraps or pita bread and toss pasta in it for a delightful dinner.
