Microwave the frozen corn for 2 minutes. If using fresh shelled corn, add to the mixture in step 2 below instead.
I have used a mixture of minced fresh parsley, sage and oregano, but any other herbs could work instead. If using dry herbs, reduce the quantity by half.
Sprinkle the olive oil on the diced peppers and tomato, and microwave for 3 minutes.
Prepare the tortillas as per package instructions, cooking them on a griddle or microwave as instructed, and applying oil spray as required.
Spread red pepper pesto or other herby spread of your choice, on one side of each tortilla.
Heat a griddle pan (or tava or skillet) till it is smoking hot. Spray with olive oil spray or other vegetable spray, or lightly coat the surface with a few drops of oil. (see handy tip below). A griddle pan gives a nice 'grilled' look to the quesadilla.
Place one tortilla on the pan and lower the flame. Spread the peppers, tomato, corn and edamame mixture onto half the tortilla. Let it cook for one minute, and add a spoonful of mixed herbs. Sprinkle cheese evenly on the vegetables.
Fold over the top half over the fillings, and gently press the edges of the tortilla. Cook for another minute and then flip over the quesadilla so that it cooks on the other side, and the griddle marks appear all over. Remove after one minute or when the cheese begins to melt.
Remove, cut into two halves and serve hot with guacamole and sour cream or salsa.
Meanwhile, place another tortilla on the pan adjoining the first quesadilla, spread the vegetable mixture and follow the directions in steps 6 and 7 above. Alternatively, you could make the quesadillas one by one instead of two at a time.
Oil or spray the pan between each set of tortillas.
