Clean, cut and dry the Brussels sprouts.
In a bowl mix the sprouts, olive oil and seasonings together.
Add to a greased cookie sheet and bake at 400 degrees for 15 to 20 minutes.
Stir occasionally to allow to cook evenly.
Once cooked, place on a couple paper towels to remove the extra grease.
In a small skillet add the butter, chopped walnuts and sweetener (you would also add the cranberries).
Allow the nuts, butter and sweetener (and cranberries, if using) on medium heat for 6 to 8 minutes until toasted and coated well.
Once the sprouts have finished you can place all the ingredients into a nice serving dish and stir well.
