This recipe is excellent. However, I don't have a grill so the first time I broiled them on a cookie sheet with tin foil. They came out great, but I found that the marinated made them slightly runny. Next time I made them I placed them on a wire rack with a cookie sheet under it and broiled it for the same amount of time - about 5 minutes on both sides. Came out fantastic!
Update: I've made these burgers so many times now, they're that good. To add some extra flavour, chop 2-3 onions and sauté them for at least 20 minutes on low heat with olive oil and butter. Viola, caramelized onions, which taste AMAZING with these burgers. One final note for those who didn't like the vinegar taste: a good balsamic is essential. The cheap stuff (under 5 bucks) is gross and overpowering. Buy a good bottle (you'll use less) and it tastes much sweeter.
