The following is one of my alternate London Broil cooking methods.
Cut the meat in 3/8" slabs, then cut the slabs into 3/8"x3/8"x1-1/2" pieces.
Prepared a marinade as follows:
1 Cup, Olive Oil
1 Cup, 2 Buck Chuck, Red Wine
1 Cup, Soy Sauce.
Marinate the meat overnight minimum, 2 days are better, then cook as follows:
Using a cast iron Dutch oven with 1/4" hot olive oil in bottom, brown small batches of the meat, removing the browned meat to a bowl.
2 Large, Onions, cleaned and sliced, then held for further use.
When meat has all been browned, add onions and saute.
2 Cans, sliced mushrooms.
Add mushrooms to pot when onions are clear, for about 5 minutes, stirring frequently.
Return meat to pot and stir, then add remaining marinate, stir, then cover and steam for about 5 minutes.
Turn off heat and let rest for about 5 more minutes.
To Serve:
Spoon mixture over open faced Hoagy bun including some gravy from the pot, then cover with shredded mozarella cheese.
Nuke sandwich in microwave for about 30 seconds or until cheese is melted.
Screw the carbs and whatever else the diet gurus wring their hands about.
ENJOY.
