Oatmeal Raisin Crumble

6 cups rolled oats, 1/4 cup corn oil, 1/2 cup whole wheat flour, 1 cup or so of raisins, 1 cup of milk to moisten, vanilla, salt, and sugar to taste. Melt 1/4 cup of the sugar in the oil. Then toss all ingredients in a big bowl like a salad and adjust the salt-sugar-vanilla balance to suit your taste. Add a bit more liquid (I actually used a bit of tea from the morning's teapot!) if the ingredients seem dry. Pour the mixture into an oblong greased pyrex dish and bake in a preheated 350-degree oven for 35 minutes, or until it starts to brown at the corners. It will be crumbly on top but it holds together.
