Monkey Meat

Preparation : >>I am new to the group and have a request. I remember from back near "the dawn of time" the early 1970s when I was in the US Navy and stationed in the Philippine Islands. There was a substance that was somewhat disparagingly referred to as "monkey meat" that was sold along the street out side the bars. I know it was usually a pork BBQ. I have tried to get the exact flavor but have not quite made it yet. If anyone has a recipe I would certainly appreciate a response. If my memory is not failing I remember it was biased on soy sauce, lemon juice and MSG. Cooked on a wooden skewer over a charcoal grill.
