This comes from a cookbook Tom and I got years and years ago at a London healthfood store called Cranks. The original recipe calls for melted butter, but I substitute olive oil, and it apparently tastes fine. When our son came up today for Tom's birthday, this was the one thing he wanted me to make. Sadly, I couldn't get any photos because he ate them all up.
1 1/4 cups rolled oats
1-1 1/2 cups cheddar cheese
1/4 cup olive oil
Beat egg, and then beat in olive oil. Stir in oats and cheese. Put in greased 8x8 pan and bake in preheated 350º F. oven about 40 minutes.
I can't tell you what a huge, huge hit these are with our kids. Tom rarely gets to taste them.
