Preheat your cast iron skillet over medium high heat.

Add the olive oil and minced garlic.

Saute the mushrooms till soft and tender.

Toss in the spinach. Wilt the spinach and then spoon everything into a bowl and set aside.

Let the pan reheat a bit and add just a bit of olive oil.

Toss the potatoes into the skillet and before turning them, allow them to get a little crust on them. (I swear that was the best part!)

When you're ready to turn them, add the butter.

When the potatoes are nice and golden, add the mushroom and spinach mixture back in. Turn off the heat.

Top everything with cheddar cheese and then cover with a lid or plate till the cheese has started to melt.

Serve immediately.
