Caramelized Onion Mushroom Tortilla Melts with Apple Salad

Crispy pan-fried tortillas stuffed with savory caramelized onions, tender button mushrooms, and melted cheddar and Monterey Jack cheeses. The filling gets richness from mushroom stock concentrate and fry seasoning, while a fresh apple and mixed greens salad with tangy sour cream crema provides a bright contrast. Perfect for weeknight dinners or casual entertaining when you want something more sophisticated than a basic quesadilla.

FAQ
Can I make these melts ahead of time?
You can caramelize the onions and mushrooms up to 2 days ahead, but assemble and cook the melts just before serving for best texture.
What if I don't have fry seasoning?
Substitute with a mix of garlic powder, onion powder, paprika, and black pepper, or use your favorite all-purpose seasoning blend.
How long will leftover melts keep?
Refrigerate cooked melts up to 3 days. Reheat in a dry pan over medium heat until warmed through and crispy again.
