If you're using a chuck roast, pound it with a meat mallet or rolling pin to tenderize
Marinate beef or steak for at least 2 hours using this Korean BBQ marinade* (optional)
Cut beef or steak into thin slices
Heat oil in skillet
Mix together cornstarch and flour in a bowl or ziploc bag. Evenly coat pieces and cook till brown and slightly crispy
Remove steak from skillet, drain excess oil and toss in broccoli to lightly saute
While broccoli is cooking, mix together sauce ingredients in a bowl. Then remove broccoli from skillet and pour in sauce. Cook about 10 minutes or until sauce reduces by about 1/4
While sauce is cooking, cook ramen noodles per package instructions. Some of my other recipes I use a tiny bit of the ramen packet to season but not this one, since the sauce is sweet.
Dump broccoli and beef back into skillet when sauce is done, stir slightly and add in ramen noodles last. Toss all ingredients together, garnish with sesame seeds or bean sprouts if desired.
