Try loading your crockpot with big pieces of apples and pears, and a touch of cinnamon... enjoy a big bowl of stewed fruit after dinner.
I don't own a crockpot, but at home, sometimes we'd stew all kinds of fruits (apples, pears, strawberries, pineapple, plums, ... prunes, raisins...) with some sugar, a couple of cinnamon sticks, maybe a clove. Serve it with a touch of Amaretto. Yum.
