If you can make mash potato, you can make this.
Cut up some courgette and some potato and put that in a pan with water. Boil till soft. The proportion is 75% Courgette and 25% potato.
Drain and add some dill and salt
Mash up and add a bit of milk or cream and then a couple of triangles of cheese and mash that in.
I had that with the 10 minute chicken and some peas.
