--2 T white wine
--2 T apple cider vinegar
--1 T brown sugar
--2 t sesame oil
--2 cloves smashed and chopped garlic
--1/2 t crushed red pepper flakes
--1 bag thawed broccoli florets (to add later)
Add the liquid to the crockpot. Chop up your garlic and add it along with the spices to the mixture. Slice meat into thin strips (I used my kitchen scissors this time I made it and it was much easier). Toss in the liquid and spice mixture to coat.
Cook on low for 6-8 hours, depending on the cut of meat. Thicker pieces will take longer to tenderize.Add the liquid to the crockpot.

An hour before serving, add entire bag of broccoli, cover and cook on high for another hour or so.Stir gingerly to coat broccoli.
