Place a whole wheat tortilla on a clean surface or a plate.
Sprinkle half of the shredded cheese evenly over one half of the tortilla.
Distribute the diced vegetables and cooked black beans over the same half of the tortilla.
Sprinkle the remaining shredded cheese over the vegetables and beans.
Fold the other half of the tortilla over the fillings, creating a half-moon shape.
Heat a non-stick skillet or pan over medium heat.
Carefully transfer the folded tortilla to the skillet and cook for about 2-3 minutes on each side, or until the tortilla becomes crispy and the cheese melts.
Once the cheese is melted and the tortilla is golden and crispy, remove the quesadilla from the skillet and let it cool slightly.
Use a sharp knife to cut the quesadilla into wedges.
