MY mom always used to make these things she called "hobo pouches." They are beef patties with sliced carrots, potatoes, and onions in a tinfoil pouch done in the oven or on the grill. I'm trying to make them better and haven't had much luck. I started to use olive oil, and it helps, but I'm trying to make them really pop. Rosemary didn't work, and I'm out if ideas. Any suggestions?
