Pat chicken dry with paper towels. Sprinkle over Mexican Seasoning, then season with salt and pepper.
Heat a large non-stick pan over medium. When hot, add 1 tbsp (2 tbsp) oil, then chicken. Cook 5-6 min, flipping once halfway, until golden and cooked through.**
Remove the pan from heat, then cut chicken into 1/2-inch strips.
Add chicken to a large bowl.

While chicken cooks, on a clean surface, cut zucchini into 1/4-inch half-moons.
Roughly chop the cilantro.
Once chicken is finished cooking, carefully wipe the pan clean. (NOTE: Set aside off heat! We'll use it again in Step 4!)
3
Add cheese to the large bowl with chicken, then stir to combine.
Brush 1/2 tbsp (2 tbsp) oil over one side of tortillas.
On a baking sheet, arrange tortillas, oiled-side down. (NOTE: For 4 servings, divide tortillas between 2 parchment-lined baking sheets.)
Divide chicken-cheese mixture to evenly over one side of each tortilla.
4
Fold tortillas in half, gently pressing down, to enclose filling. Place another baking sheet on top. (TIP: This keeps the quesadillas from puffing up and opening when cooking!)
Bake in the bottom of the oven for 7-8 min, flipping halfway through, until cheese melts and quesadillas are golden. (NOTE: For 4 servings, bake in the bottom and middle of the oven, rotating sheets after flipping.)
5
Meanwhile, heat the same pan over medium-high. Once hot, add 1 tbsp (2 tbsp) oil, then zucchini and corn. Cook for 4-5 min, until tender crisp.
Add remaining Mexican Seasoning. Cook for 1 min, until fragrant. Season with salt and pepper.

Stir cilantro into jumble.
Once quesadillas are golden, cut each one into three pieces.
Divide mini quesadillas and jumble between plates.
