The first step of this easy chicken quesadilla recipe is to chop all the veggies and the chicken into small pieces or slices. I prefer to slice the mushrooms.
Put oil in a pan, then add the chicken first, followed by the onion. Season them with salt and pepper.
When the chicken is white on both sides, add the bell pepper and the tomato.
If you want to spice things up, at this point, you can add the jalapeno, too.
Add 50 ml chicken broth or water to the pan, so the ingredients don't burn until the pepper gets cooked.
Add the mushrooms, then will up the pan with hot water or chicken broth just until the ingredients are covered.
Now you can add the garlic, and if you want to use chilli powder, you can add that too.
Cook it on medium heat for about 20 minutes, but check the chicken if it's ready before all the water is gone. Leave it to cook just until there's a little bit of sauce left on the bottom of the pan!
In a large and wide pan, heat up a tortilla, and put some grated cheese on top of it.
When you see that the cheese is melting, add the veggies and chicken on one side and fold the tortilla in half. Leave it like that for 2-3 minutes on the lowest heat. That's it, your chicken quesadilla is ready to serve!
