Rinse your beef in vinegar and water. Pat dry to remove excess water.
Mix the sauce ingredients in a small bowl and set aside.
Season beef strips with marinade ingredients in a bowl as listed above. Set aside for 2 hours or overnight.
Over high heat oil in a large frying pan, saute onion, cabbage, and carrots for 1-3 minutes. Add the white part of the onion and remaining vegetables except the pepper and stir for another minute.
Remove vegetables and set aside.
In the same pan over medium heat, fry beef strips for 3-5 minutes or until brown. Do it in batches to prevent overcrowding.
Remove beef. Deglaze the pan with the sauce and add back the cooked beef, then stir to coat your beef and allow the sauce to thicken.
Once the sauce thickens, add scotch bonnet pepper, stir-fry vegetables, and combine everything. Top with green parts of the escallion and cover for 1-3 minutes, then remove heat.
Serve.
