Preheat oven to 400°F and line a large baking sheet with parchment paper.
02 -
Combine cauliflower florets with olive oil, ground cumin, smoked paprika, garlic powder, chili powder, and salt on the prepared baking sheet. Toss to coat evenly and spread out in a single layer. Roast for 15 minutes until tender.
03 -
While the cauliflower roasts, heat a skillet over medium heat. Sauté diced onion, red bell pepper, and minced jalapeño in a small amount of olive oil for 3 to 4 minutes until softened.
04 -
Add roasted cauliflower to the skillet with sautéed vegetables. Cook together for 2 minutes, stirring to incorporate flavors. Remove the mixture from heat.
05 -
Lay out the flour tortillas on a clean work surface. Using a sharp paring knife, cut jack-o'-lantern faces into two of the tortillas to form decorative tops.
06 -
Evenly distribute the cauliflower-vegetable filling and shredded cheddar cheese onto the two uncut tortillas.
07 -
Place a cut-out tortilla on top of each assembled tortilla, aligning edges and gently pressing down to seal.
08 -
Heat a large nonstick skillet over medium heat. Cook each assembled quesadilla for 2 to 3 minutes per side, until the tortillas are golden brown and the cheese is fully melted.
09 -
Transfer cooked quesadillas to a cutting board. Insert a thin green onion slice into the top edge of each to resemble a pumpkin stem.
10 -
Cut each quesadilla into wedges and serve immediately with salsa, guacamole, or sour cream as desired.
