Prepare the Vegetables: Start by coarsely chopping the green peppers and slicing them into thin strips along with the onions. Place the sliced veggies in a bowl and set aside.

Marinate the Beef: In a large mixing bowl, combine your cooked shredded beef with the lime juice, minced garlic, salt, and pepper. Let the mixture marinate for 1.5 hours.

Heat the Skillet: Heat a large skillet over medium-high heat, adding a splash of oil. Once the oil is shimmering, add the marinated beef mixture and cook until crispy.

Add the Vegetables: Fold in the sliced green peppers and onions with the beef in the skillet. Cook undisturbed for another 3-5 minutes.

Stir and Crisp: Gently turn the mixture and fry for an additional 3-5 minutes until everything is caramelized beautifully.

Serve It Up: Remove from heat and serve your Cuban crispy shredded beef with sides like rice or tortillas.
