Dice the meat into tiny pieces. Place the meat in a mixing bowl and add 2 tablespoons oil, ginger, garlic, red pepper flakes and 2 tablespoons soy sauce. Mix together in circular motion until well mixed. Let marinate in refrigerator for 4 hours.
Mix together the citrus juices, soy, and hoisin sauce with a whisk. Reserve until needed. Clean the romaine lettuce, chopping off the stem, peeling each ‘spear’ and running under clean cold water. Reserve in refrigerator until ready to use. Chop scallions into rings and reserve chilled.
Coat a very hot saute pan lightly with oil. Lay the meat around the saute pan being careful not to lay too many on top of each other. Sear the meat until crispy and golden brown, about 2 1/2 minutes. Once meat is brown, toss gently in pan and sear another 2 1/2 minutes. The pan will appear to “burn”, but that is the carmelization and where all the flavor comes from.
Add 1/2 of the citrus soy mixture to the saute pan and coat well. Let the sauce coat the meat until it is glazed, and thickens on the meat. Add more or less depending on how “wet” you want your mixture. Spoon meat onto a serving bowl. Wrap the chicken mixture in romaine lettuce and top with scallion rings. Serve and enjoy!
