Heat a medium skillet over medium heat. Warm your tortilla for about 30 seconds, flipping halfway. Flip once more, then sprinkle one-half of the tortilla with about half of the cheese. Cover the cheese evenly with the remaining fillings: beans, bell pepper, onion, 1/2 tbsp cannabis oil, jalapeƱo and chicken (if using).
Sprinkle the remaining cheese over the fillings, and fold over the empty side of the tortilla to enclose the fillings. Quickly brush the top of the quesadilla with light coating of remaning 1/2 tbsp cannabis oil, then carefully flip it with a spatula.
Let the quesadilla cook until golden and crispy on the bottom, about 1 minutes, reducing the heat if necessary to prevent burning the tortilla. And flip it over once more and repeat.
Transfer the cannabis quesadilla to a chopping board and cut in 3 pieces. Serve with guacamole, sour cream or any other salsa you like.
