Bircher Muesli

Note that all the ingredients are variable. I like my muesli thick enough that a spoon will stand up straight if stuck in; a lot of people like it thinner.
Adding more liquid and let it sit a bit for a thinner, creamier muesli.

1 medium-coarse chopped apple (red or golden delicious work well)
1/2 cup raisins
1 banana in 1/4 inch slices
1 orange, chopped
1 cup oats (or as much as you need to get desired thickness)
1 non-fat fruit yogurt (can use non-fat milk or even soy-milk instead)

From here it is improvisation. I chop in a cup of whatever fruits are
in season, in particular, strawberries, peaches, blueberries, nectarines,
even mango, plums, prunes, pears, pitted cherries.
