Cut your avocados in half lengthwise and remove the pits. Rub the insides of the avocado with a few drops of lemon juice from a fresh lemon slice (If you are eating these right away, you can leave out the whole lemon part - the lemon just helps keep the avocado from turning brown). Crumble the bacon and stuff it into the avocado half where the pit was – use one piece of bacon per avocado half.
Over low heat, melt the butter, balsamic and garlic. Stir constantly for about a minute or two until the mixture is boiling. As soon as it boils, remove from heat and drizzle all over the avocado halves. Enjoy!
