Oil a baking pan and start the oven at 400 degrees. Cut onions until diced and spread on pan. Take any size potato and chop into quarters so that you may be able to cut pieces that are very thin about the size of your pinky finger. Spread on pan and spice with salt and pepper, also rosemary, thyme, oregano, celery leaves (basically any green spice will taste great). Plop in oven and let bake for about 45 minutes or more until they are soft enough for a fork to go through, stirring occasionally. Then enjoy them!
