1Mix all ingredients except the parmesan cheese in a large ziplock bag. Let flavors marinate for 10 minutes or so.
2Put on a grill over medium heat, turning frequently until crisp tender. About 10 minutes. (Use one of those special grill skillets or a cast iron skillet if you are worried about losing beans through the cracks.)
3Remove beans from heat, sprinkle with parmesan cheese. Easy!
