In a large bowl, add beef, garlic, sofrito, soy sauce, adobo, sazon, oregano, and lime. Mix until the beef is well coated with the seasonings.
Heat oil in a pot over medium heat. Add sugar to the hot oil and let it caramelize.
Add the beef to the pot and cook, covered, for 5 minutes. Turn the beef pieces and continue cooking, covered, for another 5 minutes or until all juices are absorbed.
Add tomato paste and 1 cup of water to the pot and let the beef cook for 15 minutes, covered, or until most of the liquid is absorbed.
Repeat this process two more times, adding 1 cup of water each time and allowing the beef to cook for 15 minutes each time, or until most of the liquid is absorbed.
Add the sliced onion and bell peppers to the pot along with the last cup of water and cook for 10-12 minutes covered, or until the sauce thickens and the vegetables are tender. ¡Buen provecho!
Notes
Store in the fridge for 2-3 days or freeze for 1-2 months. Defrost in the fridge or with the microwave. Reheat on the stovetop or in the microwave, adding water if needed, and a squeeze of lime juice to freshen the taste.
