Slice the bacon into small chunks and cook it in a skillet over medium-high heat, until crispy. Remove with a slotted spoon and drain on a plate lined with paper towels.
Layer the salad into the tumblers, starting with the lettuce and then working your way through the other ingredients. If you plan on eating the salad soon, pour the dressing in or if you'll be eating it later, pack the dressing in a separate container. Enjoy!
