Place a medium-size skillet over medium-high heat with 1 turn of the pan of EVOO, about 1 tablespoon. When the pan is hot, add the turkey bacon and cook until crispy, 3-4 minutes per side (cook this is batches if need be, adding a few drops of EVOO to the pan before starting a new batch). When the bacon is finished cooking, transfer it to a paper towel-lined plate to drain any excess grease.

While the bacon is cooking, stir together the ranch dressing and crumbled blue cheese. Portion the dressing out into four small, re-sealable containers and reserve the dressing until you're ready to eat your sandwich.

Assemble the sandwiches by laying down four toasted slices of bread and topping each with a couple of lettuce leaves, a few slices of tomato, a few slices of avocado, a small handful of chicken breast and three slices of turkey bacon. Top each sandwich with a toasted sliced of bread and build another layer, repeating the first with the remaining ingredients. Cap off each sandwich with the remaining pieces of bread and wrap them up or place them into a re-sealable container.
