Season the salmon pieces with sazon, adobo, salt, and pepper to taste. Set aside.
In a large pot over medium heat, add oil, tomato, garlic, onion, bell peppers, sofrito, tomato paste, oregano, and capers. Cook for 5 minutes, or until vegetables are softened.
Add water to the pot and bring to a boil. Add salmon to the pot and mix. Cover with lid and cook for 5-10 minutes, or until salmon is fully cooked and sauce has thickened.
Remove from heat, add lime juice, and serve. ¡Buen provecho!
