Is It Frittata or Is It Quiche

Step 1: Combine egg and milk adding salt (if using) and pepper and whisk well together.

Step 2: Melt butter in frypan/skillet over a medium heat and cook mushrooms till tender and there is no liquid, transfer to a plate.

Step 3: Put the tortilla into the frypan/skillet, brown on one side and turn.

Step 4: Scatter cooked mushrooms over the tortilla and half the cheese.

Step 5: Pour eggs over the mix and rest of cheese.

Step 6: 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, halve if serving two.

Step 7: Slide onto plate/plates and serve.

Step 8: VARIATIONS - I have since made this several times and sometimes changing it for what I have on hand, for instance instead of a tortilla I have used flat bread, wraps or a thin pizza base and for other ingredients I have added crispy bacon, onion, tomato or used a mix of cheeses (sharp cheddar, parmesan and mozzarella). You could also make smaller ones by purchasing or making smaller tortilla wraps.
