Preheat oven to 400 degrees. (I use my toaster oven, set on the convection roast setting.)
Add oil, salt and pepper to a 1-gallon plastic bag.
Wash and trim Brussels sprouts. (Remove ends of stems and any discolored leaves.)
Slice Brussels sprouts in half lengthwise and then place them in the bag with the oil.
Shake bag to coat Brussels sprouts evenly in oil.
Line a shallow baking pan with parchment paper.
Spread Brussels sprouts in a single layer in the pan and roast for about 15 minutes.
Turn Brussels sprouts with a spatula and continue roasting for another 15-20 minutes until they are tender but not overcooked.

Note: Nutrition information is a rough estimate for special dietary needs.I subscribe to the theories presented in the book Whole and believe we should focus on eating a variety of whole foods instead of counting calories or keeping track of individual nutrients.
