I am a huge fan of beef satay and have finally settled on a recipe I love:
Frying steak
Stir fry vegetables
2 tbsp peanut butter (I use 1 smooth, 1 crunchy)
2 tbsp soy sauce
1 tbsp Worcester sauce
Few drops Tabasco sauce (add lots if you like it spicy!)
1 tbsp brown sugar
1/2 beef oxo cube
Method:
Stir fry meat and veg. In separate bowl mix the rest of the ingredients and dump on top of the beef.
It will be rather solid and I add some boiling water to help it melt and make a nice sauce for the beef.
Then pop it on top of rice or noodles and you have a delicious meal!
