Cut the spinach, mushroom and potato small and grate the cheddar.

Whisk the egg with the cream.

Melt the butter with the oil in a small pan and cook the potato and mushroom until tender.

Stir in the spinach, then pour in the egg and season lightly.

Sprinkle the cheese over and cook gently until the egg sets; fold in half, or finish under the grill for a browner top.
