Mix the vinegar, salt, garlic, pepper, & soy sauce & into a large flat pan. Lightly pound the steaks with a meat mallet then place into the pan with the marinade. Cover & refrigerate for 6-12 hours. Be sure to turn the steaks every 3-4 hours.
Mix all the stuffing ingredients (last 7) together. Place the steaks out flat and cover with the stuffing mixture. Roll the steaks up and pin them closed with stainless steel meat skewers. Bake in a pre-heated 350 degree F. for 1 hour. Baste with the marinade twice during the hour. Place on top oven rack and broil for 3 minutes. Slice the rolls across & serve. This is excellent with wild rice. The marinade may be thickened and made into a gravy/sauce for this as well by adding 2 T of peanut oil and cornstarch as needed.
