Preparation
Preheat oven to 375°F.
Arrange bacon on a slotted baking sheet and bake to crisp, 15-18 minutes. Once cooled crumble into bite-size pieces.
In a large sauté pan, heat EVOO over medium-high heat. Brown beef, season with salt and pepper, and remove to plate.
Warm chips slightly in oven on baking sheets. Remove and top with ground beef, blue cheese, bacon bits and shredded Monterey Jack cheese. Place in oven for 5-10 minutes, or until cheese melts.
Garnish with romaine, scallions and sour cream.
