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.
