Is It Frittata Or Is It Quiche - cooking recipe

Ingredients

1 cup mushroom (sliced, I used button or small cup)
1 tablespoon butter
1 (10 inch) tortillas (to fit frypan or skillet)
3 eggs
2 tablespoons milk (I use hi-lo which is low fat)
salt and pepper (I don't use salt but I am generous with freshly ground pepper)
1 cup cheese (grated, I use tasty or cheddar)

Preparation

Combine egg and milk adding salt (if using) and pepper and whisk well together.
Melt butter in frypan/skillet over a medium heat and cook mushrooms till tender and there is no liquid, transfer to a plate.
Put the tortilla into the frypan/skillet, brown on one side and turn.
Scatter cooked mushrooms over the tortilla and half the cheese.
Pour eggs over the mix and rest of cheese.
Pull the egg mix from the edge of the frypan/skillet and swirl the uncooked mix to the edge, when nearly cooked (will still be wet at the centre), put under the grill/broiler and finish cooking till set.
Slide onto plate and halve and serve.
