Place Butter, Sugar and Salt in a mixing bowl.
Cream together until light and fluffy.
Slowly work in the Flour until a crumbly dough forms.
Add the Toffee Chips and work in with a spatula (it works better than the mixer does)
Place on a large piece of waxed paper.
Press the crumbly dough into a log.
Roll the waxed paper around it and roll on the counter (this seems to work fairly well)
Remove waxed paper and wrap in plastic wrap, then refrigerate for 4 hours.
When you remove the dough from the refrigerator, begin preheating the oven to 325 degrees.
Slice into ¼ inch slices and lay them out on a parchment lined baking sheet.
Bake for 20-25 minutes, just until the bottoms begin to brown but the sides are still pale.
Leave the Shortbreads on the baking sheet for about 5 minutes to give the hot toffee bits a chance to cool a little bit, cause they are gonna be REALLY hot and REALLY sticky.
Move to a wire rack and let cool completely.
Serve with your favorite herbal tea.
Or just eat them one by one....YUM!
