Slice the chorizo lengthwise in half, then cut each half into approximately 5 mm thick slices.
Heat a pan over medium-low heat, add the chorizo slices, and fry for 3-4 minutes until crispy and cooked through (no oil needed—chorizo releases its own fat).
While the chorizo cooks, cut the spring onions into thin rings and chop the jalapeños.
Remove the cooked chorizo from the pan and place on a plate.
In a bowl, mix the chorizo with the spring onions, jalapeños, and grated cheddar cheese.
Wipe the pan with a paper towel to remove the excess fat.
Place a wheat tortilla in the pan over medium-high heat.
Top the tortilla with the cheese mixture.
Place another tortilla on top and press gently.
Cook for 1 minute until the bottom is lightly golden brown, flip, and cook the other side for 1 minute until lightly golden brown.
Remove the quesadilla from the pan and cut into 8 equal pieces.
Serve hot with dips such as guacamole or sour cream.
