Haitian Tasso Steak Bites

In a large bowl, combine the chopped onion, minced garlic, chopped scallions, chopped parsley, chopped bell pepper, and chopped thyme leaves. Add the vinegar, and mix well.
Add the cubed meat to the bowl, and toss to coat with the marinade. Cover the bowl and refrigerate for at least 2 hours, or overnight for best results.
In a small bowl, mix together the cayenne pepper, paprika, salt, and black pepper.
Remove the marinated meat from the refrigerator, and drain off any excess marinade. Coat the meat evenly with the spice mixture.
Heat the vegetable oil in a large skillet or grill pan over medium-high heat. In batches, sear the meat on all sides until browned and crispy, approximately 3-4 minutes per side.
Once all the meat has been cooked, remove it from the skillet or grill pan and place it on a serving platter. Serve the Tasso with your choice of side dishes, such as rice and beans, fried plantains, or pikliz.
