I butterfly the breast and put jalepenos inside it, then wrap it in bacon and put some tooth picks into them and grill it. My mouth is watering now

If you are cooking the breasts. I wrap them in bacon and grill them. I actually just had it last night it was really good. You can also season it with any seasonings you like.

try marinating it in italian dressing and grilling. it tastes pretty good

Here's a good tip for tender duck breast. Cut the filet off each side. It should look kind of like a small ribeye steak. Place each steak on a cutting board and tenderize it with a Jaccard meat tenderizer. They have this tool at Cabelas and the neat thing is it will tenderize a steak yet not change the texture of the meat. The thirty-six tiny sharp blades do not bruise the meat like a mallet or cube steak machine. They just cut the tendons in the muscle that make meat tough. Next marinade and grill. A duck hunter staying in the room next door in a mom and pop motel near Cheyenne bottoms waterfowl refuge showed me this trick. Best duck I have ever tasted.
