Spread the garlic on the meat then set aside to marinate for about an hour or two.
In a pan over medium heat, add the oil, then onions and sauté until almost golden-brown
Add the marinated beef, cook for about 5 minutes or until you seal the pores (when meat changes color). Add the Knorr beef cubes and mix well, then add tomatoes.
Cook for another 10-15 minutes or until all the liquid has evaporated and the mixture has a thick consistency and coats the beef and the beef is super soft.
Finish off with some lime juice and cilantro and then serve.
