thanks for the fond memory, claire.
my mom always helped us make ours pizzas on english muffins. well suited to little hands.
my little guy makes his own "crabby patties" sometimes when dw cooks. he grabs some of the ingredients she's using (pre-cooked or not requiring cooking), mixes them up into what they call machie-pachie, then puts it on a burger roll and squishes it together.
the worst part is he forces us to taste it as he beams with pride.
