you seriously need some cheese. what is a meal without cheese?
Make some sort of badass pita/ taco. =D
I’d just make an onion omlette with a side of mashed potatoes.
Five easy steps.
Get all your ingredients into a large pot.
Place a chopping knife, grater and wooden spoon into the pot
Throw all that shit away
What the fuck is wrong with you?
You could take a potato bake it, cut the top off and take out the the inside make sort of mashed potatoes adding the onion, mushroom and a few spices. Then cook your mashed potatoes. Then you can put it back in the potato and add whatever else you have that would be good.
Edit: You could also make potato soup with the stuff you have.
