1Preheat oven to 450 Degrees F.
2Line baking sheet with aluminum foil, brush with approx 1 tbsp Canola oil and set aside.
3Prep the chopped and minced ingredients, plus the spices, and place them at arms length of the stovetop.
4Heat 1 Tbsp Canola Oil in the frying pan over medium-high heat. Add the mushrooms and onions and season with salt & pepper, stirring once. Cover, and lower heat to med-low, cooking for 9-10 minutes. Set a timer, and uncover and stir at the half way mark.
5Next, stir in the garlic, coriander and red pepper. (The mushroom-onion mixture will be significantly reduced. If the pan appears to have some burn marks, do not worry as this happens a a matter of course when mushrooms reduce down. They are not burned and you’ll notice that the pan deglazes as you continue to stir.) Stir/cook for :30 – 1 minute.
6Add the Swiss Chard and cover immediately to wilt. Cook covered just 1-2 minutes, then uncover and continue to cook, stirring regularly as the mixture continues to reduce, another 4-5 minutes.
7Remove the pan from the heat, add the cider vinegar and stir to incorporate.
8After a few moments cooling, mix in the cheese and cilantro.
9Set the tortillas on the prepared baking sheet and spread the filling over *one half* each tortilla, leaving a small boarder next to the edge. Fold the tortillas over, creating half-moons, to cover the filling. Brush the top half lightly with the oil.
10Bake at 450 for ten minutes or until tortillas being to brown, then, carefully flip them using a spatula. After ten minutes in my oven they were browned through but still needed a little cooking time on the flip side, so I killed the heat and baked three more minutes.
11(So that the Greek Yogurt wouldn’t create too great a temperature contrast, I removed the amount I’d be using from the fridge right after putting the quesas in the oven, to let it come closer to room temp.)
12Remove quesadillas from heat and allow to cool on a wire rack 5-10 minutes.
13Cut each half-moon into four pieces and serve with dollops of Greek Yogurt, plus a sprinkle more cilantro. They will go fast!
