Break up pecan pieces and place a small amount in each tart shell.
*You can make the filling fill more tart shells if you use more pecans* Melt margarine in a saucepan and then add the rest of the ingredients.
Bring to a boil, stirring a few times with a whisk.
Let boil for 2 minutes.
While mixture is still hot fill tart shells and top with 1 chocolate melting wafer or a few chocolate chips. **or melt chocolate in a ziploc bag, cut off one end,and drizzle over tarts**.
Cool and enjoy!
These also freeze well. Place cooled tarts in a Tupperware container or a ziploc bag. (You can use wax paper to separate the layers if desired) Label and Freeze. To serve: remove tarts from container and let come to room temperature and then enjoy!
