Prepare your fillings – grate the cheese, de-seed and chop the peppers.
Lay a tortilla wrap in a frying pan. Spread the pesto all over the tortilla, leaving a small gap around the edge.
Sprinkle the grated cheese over the top of the pesto. Scatter over the chopped peppers or other fillings** of your choice. Place the second tortilla on top to form a sandwich with the fillings in the middle.
Dry-fry the tortilla for a couple of minutes until the base is golden. Once the base is cooked, pop a plate on top of the pan and flip the pan over, then carefully slide the quesadilla back into the pan to cook on the other side. Cook for a few minutes more until the cheese is melted and the quesadilla cooked through.
Slide the quesadilla out of the pan and onto a chopping board and cut it into 6 wedges. Place on the plate or platter that you'll be serving it up on.
Slice the cherry tomatoes in half, and add one half to the tip of each quesadilla wedge for the reindeer noses.
Cut the olives into rings, then add two rings to each quesadilla wedge for the reindeer eyes. Place 2 pretzels on each quesadilla wedge for the reindeer antlers.
