Lay the bacon on a sheet tray and cook in a 400°F oven until crispy. Drain on paper towels and crumble by hand.
Using a mandolin, thinly slice the apples. Toss the apples in the lemon juice to prevent them from turning color.
In a bowl, combine the room temperature Roquefort and the sour cream.In another bowl, combine the honey and truffle oil.
To build the quesadillas, lay four of the tortillas on a flat surface. Spread a thin layer of the Roquefort mixture on all four tortillas. Top two of the tortillas with the sliced apples as you would layer mozzarella cheese on a pizza. Top the apples with a sprinkling of the crumbled bacon and shredded Monterey Jack. Top with another tortilla.On that tortilla,place additional layers of apples, Monterey Jack and bacon. Top with the Roquefort tortillas, spread-side down.
Cook quesadilla in a nonstick sauté pan sprayed with PAM over medium-high heat for 2-3 minutes per side or until crispy and golden. Cut each quesadilla into 8 triangular wedges.
Garnish with a drizzle of truffle honey, chopped chives and cracked black pepper, and serve.
