Creating Southwestern Chicken Quesadillas is straightforward when following these clear steps:

1. Prepare Ingredients: Gather and chop all ingredients before starting. This will streamline the cooking process.
2. Cook Chicken Mixture: In a skillet, heat olive oil over medium heat. Add the red onion and bell peppers. Sauté for about 3-4 minutes until softened.
3. Add Chicken and Spices: Stir in the shredded chicken, corn, black beans, and taco seasoning. Cook for another 2-3 minutes until everything is well combined and heated through.
4. Assemble Quesadillas: On one half of a tortilla, layer a portion of the chicken mixture and top with cheese. Fold the tortilla over.
5. Cook Quesadillas: In the same skillet, add more olive oil if necessary and place the folded quesadilla carefully. Cook for 2-3 minutes on each side until they turn golden brown and the cheese is melted.
6. Repeat: Continue the process for the remaining tortillas, making as many quesadillas as desired.
7. Slice and Serve: Cut each quesadilla into wedges and arrange them on a serving platter.

These steps will guide you through making delicious Southwestern Chicken Quesadillas with ease.
