Preheat the oven to 180 degrees C (gas 6, 400f), and line a 12 hole muffin tin with cases
Heat the garlic oil in a large pan and add the grated nutmeg followed by the spinach
Allow the spinach to wilt down, remove it from the pan, let it cool then squeeze out and drain any excess liquid then roughly chop and set aside, allow to cool for 5 minutes
Place the gluten free self raising flour, salt, chopped spinach and most of the grated cheese into a large bowl
Use a jug to measure the milk and olive oil then whisk the eggs into the liquid
Pour the egg, milk and oil mixture into the bowl containing the other ingredients and mix to combine
Fill the muffin cases ¾ full and sprinkle with the remaining cheese
Bake for 20-25 minutes until golden (a skewer inserted in the centre should come out clean)
Cool on a wire rack, any leftover muffins can be frozen
