Low carb chicken and leek pie filling
Melt the butter in a large saucepan. Add the sliced leeks and gently cook for 5 minutes, stirring occasionally, until they are wilted and cooked.
Remove from the heat and place the leeks in a heatproof small bowl. Try to keep as much of the butter in the saucepan as you can.
Using the same saucepan with the butter, now add the diced/cubed chicken and place back on the stove top. Heat and stir until the chicken is completely cooked through to the centre of each piece.
Lower the heat and add the full fat cream cheese to the saucepan with the chicken. Stir until the cream cheese melts. Cook for a further 3-5 minutes very gently so the cream cheese thickens and creates it's own sauce. Turn the heat off.
Stir through the cooked leeks, grated/shredded cheese, salt and pepper. Mix.
Add the eggs. Mix again.
Pour the low carb chicken and leek pie filling onto the cooked pie crust.
Bake at 180C/ 160C fan/ 350F for 20 minutes or until golden on top.
