How many weight watcher points in a blt sandwich?

It all depends on how much mayo or salad dressing you like on your sandwich I like about 4 Tblsps.

11 points if you use Fat Free Mayo. The bread is 3 points per slice (6), bacon is 4 points for 3 slices (10), Mayo is 1 points for 4 Tblsps (11) and the lettuce and tomatoes are 0 points.

18 points if you use Miracle Whip. The bread is 3 points per slice (6), bacon is 4 points for 3 slices (10), Miracle whip is 8 points for 4 Tblsp (18) and the lettuce and tomatoes are free.
