When on the road, I like to eat at Taco Bell. It’s a special treat since I don’t do it at home.
If I need to stop for gas, I sometimes get a Reese’s Peanut Butter Cup 2-pack. The traditional one, not all the various permutations they’ve come out with.
When I’m home, my guilty pleasure is sitting at my kitchen table, listening to a podcast and watching a tiger swallowtail waft around my front yard . . . while ostensibly working. <grin>
Simple guilty pleasures.
