I made these today after watching Michael Smith make them on Chef at Home. My mouth was watering while watching him grill the burgers, so I just had to try them. I luckily had everything on hand and they took no time at all. They're really, really good!
I made 8 really big burgers on my barbecue, but the recipe states you can make 12 regular sized burgers if you prefer.
