1Make as many or as few as you want.
2Put pretzel on a cookie sheet and top with one Rolo per pretzel. Bake in a 200 degree oven for 3 - 5 minutes. (Just watch to make certain they don't melt). They just need to be softened.
3Remove from oven and press the pecan half down into the Rolo. Put on wax paper to cool.
