Here's my recipe. I double it to make 8 lbs because that fills up my dehydrator.
4 lbs round steak (I buy at the Mexican market, it's thin sliced for beef Milanesa)
1 cup Soy sauce
1 cup Worcestershire sauce
4 tbsp onion powder
1 1/3 tsp garlic powder
1 1/3 tsp black pepper
1/2 packet Good Seasons Italian dressing mix
1/2 small can chipotle chiles in adobo
Mix in a blender, pour over sliced meat and marinate for 24 hours.
You can dry in a low oven (150-175 degrees) for 8 hours or a dehydrator.
This is the one I have...
