Add rolled oats, cinnamon, nutmeg, cloves, salt and pecans to a large mixing bowl. .Pour in the maple syrup, olive oil and fresh orange juice. Use a wooden spoon to thoroughly combine.
Line a cookie sheet (or half sheet pan) with parchment paper. Spread granola on the parchment paper as thinly as possible.
Bake at 350 degrees for 16-18 minutes. Halfway through (at the 8 minute mark), remove the granola from the oven and stir the oats. Return to the oven for another 8 minutes. Keep an eye on the pecans to make sure they don't burn.
Remove from the oven and let cool for 5 minutes before transferring to a storage container. Store refrigerated for up to 7 days.
One small orange will yield about 2 tablespoons of orange juice. Choose a clementine, tangerine or cutie.
I recommend using an oven thermometer. Oven temperatures can vary widely and the only way to know if your oven is the temperature it says it is is to use an oven thermometer.
