Heat 1 tablespoon of oil in a large saucepan, add the onion and half a tablespoon of salt. Turn down the heat to low and cook for 20 minutes stirring occasionally.After 20 minutes add half a teaspoon of brown sugar, stir and cook for another 5 minutes
Turn up the heat to medium, add the garlic, spices, oregano and cook for a minute or two. If the pan starts to stick add a small splash of water.
Now add remaining oil then the tomatoes and mushrooms and cook for about 5 minutes until the tomatoes are a little soft and the mushrooms are cooked. If the pan gets a little dry add a splash of water. Finally, stir in the spinach and the coriander/cilantro. Cook until the spinach has wilted, about two minutes.
Use a pan large enough for the tortilla, wipe a little oil on the pan. Place one tortilla on the pan, sprinkle some of the grated cheese on the tortilla then add ⅓ of the mushroom and spinach mixture. Sprinkle more cheese on top then cover with another tortilla.
Cook over medium heat for about 3 or 4 minutes then carefully using a spatula flip the quesadilla over and cook the other side for about 2 minutes.Repeat for another 2 quesadillas. Keep them warm in the oven until they are all done.
Pop the quesadilla on a plate or board and cut into quarters, serve with a dollop of sour cream and lime wedges.
Notes
Tortillas - I use corn tortillas for these, they really work well but you could use flour tortillas if you prefer. Go for a medium-size tortilla, mine measured in at
Cheese - mature/sharp cheddar cheese works best here, make sure and grate it yourself for best results.
Can I make this vegan? You can swap the cheddar for your favourite vegan cheese, just make sure it melts well.
Can I make these gluten-free? Just make sure your tortillas are gluten-free.
