Mince the garlic and set it aside.
Slice the onion into half-moons and cut the bell peppers into strips. Set aside.
Place the chicken breasts in an electric pressure cooker. Top with the garlic, spices, and sliced onions and peppers.
Add the can of tomatoes (with juices) and tomato paste.
Place the lid on the pressure cooker and lock it. Cook for 25 minutes on high pressure. Allow the pressure to release naturally.
Shred the chicken with two forks. Salt to taste.
Serve the ropa vieja in a bowl, over rice*, in tacos, etc.
Notes: This ropa vieja is great served over my Cilantro Lime Rice!
