Then I discovered the "Oatmeal Casseroles" page in 1968's Favorite Recipes of America: Casseroles Including Breads. (I am not really sure how breads count as casseroles, but I always find afterthoughts at the ends of titles to be quite charming. The editors are more worried about utility than unity, and choose substance over style. It just seems so quaint.)
Anyway, since I like my peanut butter oatmeal, the title of this recipe did not strike fear into my heart as quickly as it could have:
At least the title of the other recipe tells us right up front that we are in for something scary:
Cottage cheese baked with oatmeal and topped with a clove-spiked tomato sauce. Yum.
I imagine these recipes were included to help families with tight budgets; the casseroles are made with cheap ingredients and have a good amount of protein without costly meat. Here substance over style comes into actual practice, and I have to admit I find myself significantly less charmed.
