I'm cooking my own Father's Day meal too. I can't think of a better Father's Day than one spent with family around my grills!
I'm doing surf-n-turf...my dad is a transplanted Bostonian and lobsters are his favorite.
Steamed lobsters. I put a chimney of K in my firepit, place a cooking grate over them and steam the lobsters in my turkey fryer pot...works great.
Bacon wrapped filets on the OTG.
