For left over pancakes we make them into peanutnut or almond butter and jelly sandwiches. (I have two kids allergic to peanuts.)
Left over baked or mashed potatoes we make into hash browns or
mash them up and scramble them into eggs with some spices.
Left over rice can be made into rice pudding if it doesn't have hot spices in it.
Left over vegetables we use in omlettes, scrambled eggs, a casserole or soup.
Left over meat can be made into sandwiches with either of these on the sandwich(ketchup , mustard, or relish.) and of course lettuce or alfalfa sprouts.
In a magazine one time I saw some uses for left over oat meal, or cream of wheat. The suggestion was to make them into
"sundaes" put on raisens, chocolate chips, dried fruit, syrup or anything that you would put on sundaes. We cann't do most of this because I have a few children that are allergic to refined sugar.
Hope these ideas help.
