Cook the Mushroom Filling

• Heat 2 teaspoons oil in a large skillet over medium heat
• Add diced mushrooms
• Cook for about 5 minutes, stirring occasionally

• Stir until everything is coated and saucy
• Lay tortillas flat
• Sprinkle 3 tablespoons cheese on one half
• Add about 1/2 cup filling
• Fold over and gently press

Cook the Quesadillas

• Wipe out the skillet
• Heat remaining 1 teaspoon oil over medium heat
• Cook quesadillas 3–4 minutes total, flipping once
• Look for crispy golden tortillas and melty cheese inside.

Slice & Serve

• Cut into wedges and serve hot.

Serving Ideas

• Fresh coleslaw for crunch
• Creamy guacamole or sliced avocado
• A side of tortilla chips and salsa
• Pickled jalapeños for extra kick
• Fresh Cilantro
• Lime wedges

Tips for Entertaining

• Make ahead by prepping the mushroom filling earlier in the day and then just reheat when ready
• Setup DIY quesadilla bar and let guests build their own with toppings like sour cream, pico de gallo, and shredded lettuce
• Cut into small wedges for easy party appetizers
• Serve on a big wooden serving board for a rustic farmhouse vibe
