My roast came out great!! The banana leaf really gave it a good flavor.
First, I cut through the length of the roast with a knife, making a cavity through the middle of it. I then stuck a link of MANDA'S garlic sausage* inside it. The outside was rubbed with 'slap ya mamma' and some fresh ground garlic/pepper. I seared the roast on the grill before wrapping it.
*MANDA'S sausage is about 12" in lenghth and can be used as a weapon if the wife comes into the kitchen and tries to tell you how to cook the roast.
