1 potato per person
1/2 an onion per person
Sheets of tin foil
2 T. butter per person

Heat oven to 350 F. Slice each potato into chunks. A medium-sized dice is what you're looking for. Dice up each onion half into a smallish dice.Grab your tin foil and roll up the sides a bit to create a boat. Add the potatoes and onions to the packet and top with pats of butter. Season generously with salt and pepper, and splash in milk. Sprinkle on thyme.Roll up sides of the packets and seal the edges tightly. Bake in oven for 45-60 minutes and serve right on the plates.
