Preheat the oven to 350°
Line a large baking sheet with parchment paper.
Place two flour tortillas side by side on the parchment paper.
Cover each tortilla with the raw Brussels sprouts, sweet potato, fresh spinach, minced garlic, and shredded cheese.
Top each quesadilla with a flour tortilla and lightly spray with olive oil.
Bake in the oven for 10 minutes, or until the tortilla tops are golden in color.
Remove from the oven, let cool about two minutes before cutting the quesadillas and serve.
