Mushroom Philly in a Pita

I got this recipe from another website and it called to put it on bread and I tried that first but this time I put it in a pita and added provolone and WOW!!! So good and so good for you. So I don't have an exact recipe , but here are the ingredients:

Pita
olive oil
mushrooms
onions
spinach
provolone

Saute mushrooms and onions in olive oil until tender. Add spinach and heat until wilted. Add cheese and melt. Put all into a pita and enjoy!!!
