Prepare the bean filling
Heat half the olive oil in a frying pan over a medium-low heat.
Add the onion and cook for approximately 5 minutes, until softened.
Stir in the garlic and ground cumin, then cook for another minute.
Add the tomato purée, pinto beans and a few tablespoons of water.
Warm the mixture through, then roughly mash the beans with the back of a fork. Season with salt and black pepper.
Griddle the courgettes
Toss the sliced courgettes with the remaining olive oil and a little seasoning.
Heat a griddle pan until hot. Cook the courgette slices for approximately 2 minutes on each side, until tender and lightly charred.
Transfer them to a plate and set aside.
Prepare the cheese
Combine the grated cheddar, chopped green chilli and fresh coriander in a bowl.
Assemble the quesadillas
Spread the mashed bean mixture over four tortillas.
Arrange the griddled courgette slices on top, then scatter over the cheese mixture.
Cover each one with another tortilla and press down gently.
Cook the quesadillas
Cook the quesadillas in batches in the hot griddle pan for 1–2 minutes on each side.
Turn them carefully and continue cooking until the tortillas are crisp and the cheese has melted.
Serve
Transfer the quesadillas to a board and cut each one into wedges.
Spoon the Fenton Farm Smoked Chilli Mayo into a small serving bowl and serve alongside the hot quesadillas for dipping.
