1. Cook bacon slices in a skillet over medium-high heat 6 minutes or until crisp; drain on paper towels, and crumble. Stir together bacon, tomato halves, and green onion in a medium bowl.
2. Brush 1 side of 2 tortillas with 1 Tbsp. melted butter, and place, buttered sides down, on a baking sheet. Layer buttered tortillas with half of bacon mixture, turkey, and cheese, leaving a 1/2-inch border. Top each with 1 tortilla, and layer evenly with remaining bacon mixture, turkey, and cheese, leaving a 1/2-inch border. Top with remaining tortillas, and gently press. Brush each with remaining 1 Tbsp. melted butter.
3. Bake at 425° for 12 to 15 minutes or until golden brown and cheese begins to melt. Gently press quesadillas with a spatula; cut in half, and serve immediately.
