Start by preparing the filling. Find a frying pan with a large base and put it on the heat. Add a drizzle of oil and let it warm up. Chop up the onion and pepper into slices and add it to the pan. Let it cook for about 5 minutes before throwing in the beans (make sure you drain them first) and any other fillings you’ve got - maybe some sweetcorn, cooked vegetables or shredded meat. Season with salt and pepper and cook for a further 3 minutes.

Scoop all the filling into a bowl and wipe the frying pan clean. Get it back on the heat and add another drizzle of oil, before carefully laying a tortilla in the pan. Scatter some grated cheese and add a put a scoop of the filling to half the tortilla.

Let it cook for about 1 minutes before flipping it over to brown the other side. Repeat with the remaining quesadillas.
