Instructions

  1. In a small bowl, combine sour cream and the juice of half the lemon. Season with salt and pepper to taste. Set aside.
  2. Heat 1 teaspoon of oil in a large non-stick skillet over medium heat. Add sliced mushrooms and cook, stirring occasionally, until browned, about 4-5 minutes. Season with fry seasoning. Transfer to a plate.
  3. In the same skillet, add 1 tablespoon of oil and the sliced onion. Cook over medium-low heat, stirring occasionally, until caramelized and soft, about 8-10 minutes. Add the mushroom stock concentrate and stir to coat. Remove from heat.
  4. Wipe the skillet clean. Place one tortilla in the skillet over medium heat. Sprinkle half the cheddar and half the Monterey Jack cheese over the tortilla. Top with half the mushroom-onion mixture. Fold the tortilla in half and cook until golden brown on the bottom, about 2-3 minutes. Flip and cook until the other side is golden and cheese is melted, about 2 minutes more. Repeat with the second tortilla.
  5. In a large bowl, toss mixed greens with the remaining lemon juice, a drizzle of oil, and a pinch of salt. Add sliced apple and toss gently.
  6. Serve each tortilla melt with a side of apple salad and a drizzle of the lemony crema.

Recipe Tips

For extra caramelized onions, cook them low and slow—don’t rush the process.

Use a cast-iron skillet for the crispiest tortilla melts.

If you prefer a spicier kick, add a pinch of red pepper flakes to the mushroom mixture.

FAQ

Can I use corn tortillas instead of flour?

Yes, but corn tortillas are smaller and may not hold as much filling. You may need to adjust the amount of filling per tortilla.

Can I make this recipe vegan?

Absolutely! Use vegan sour cream, vegan cheese shreds, and skip the cheese or use a plant-based alternative. The rest of the ingredients are naturally vegan.

How do I store leftovers?

Store the tortilla melts and salad separately in airtight containers in the refrigerator. Reheat the melts in a skillet or oven to regain crispiness.
