1 canister rolled oats
1 1/2 c. sugar
2 t. each cinnamon, nutmeg, allspice
cooking oil to moisten (about 1/2 c.)
Other good stuff
Raisins, dates, sweetened flaked coconut, chopped nuts, Rice Krispies, corn flakes, bran flakes
Mix everything in the "granola base" section but oats together, then add mixture to oats and mix thoroughly. Preheat oven to 350 and spread mixture onto baking sheets (I use two). Bake for 20 minutes, stir, then bake another 10 minutes until browned (depending on your oven and preferences, you may want to bake it another 5-10 minutes). Note: you are NOT cooking the "other good stuff."
When the oats have finished cooking, add raisins, dates, sweetened flaked coconut, nuts, rice krispies, bran flakes, etc. to stretch out the granola mixture. I generally add enough of these so that I end up with about 2 and a half canisters of granola (with 1 canister of that being the original oats--so you're adding another 2 and a half canisters' worth).
Making this is also a good excuse to buy really huge bowls if you don't already own some. Check with restaurant supply stores for inexpensive yet tough stainless bowls--Neil picked up mine at a supply store in Salt Lake and I love them dearly (also excellent for popcorn!!) This particular bowl holds all 2.5 canisters worth.
