Lay out a sheet or two of tin foil
Cover middle section with some olive oil
Drop onto to it a pile of brussels sprouts
Put a slab of butter (not margarine) on top
Sprinkle on kosher salt, garlic powder, pepper and bacon bits
Fold the edges of the tin foil around everything
Place on a grill on low heat for about 45 minutes
Every now and then, open the tin foil and turn over the sprouts so they brown evenly.
Dump into a bowl and serve. There will be no leftovers.
My wife (who used to HATE brussels sprouts) makes these. You are right; there are never any leftovers.
