Leftover garlic is a crime. Or, in my case, a myth. It’s my catnip. Whenever I have some lying around after grilling or barbecuing, I’ll make whatever excuse I need to cook it up and eat it. Like any honest addict, I eventually gave up the pretense and started mainlining it. Instead of a spoon and lighter, though, I use a grill and a spatula for mainlining my drug of choice. Grilled garlic is one of the easiest appetizers ever.
