Potato, Mushroom & Tomato Medley

Wash potatoes (as many as required for the number of people to be served) with a vegetable brush and cut into cubes. Place potato pieces on foil. Wash and cut tomatoes into cubes and place on potatoes. Slice button mushrooms and place on mixture. Sprinkle chopped (or dehydrated) onions over potato mixture. Add pepper to taste (salt also if prefered). Sprinkle bacon bits and parsley over top (parmesan cheese can be added if prefered). Sprinkle with olive oil (this will prevent burning). Fold foil and ensure that packet is wrapped tightly to avoid the oil from leaking. (Additional packets may be required depending on the number of people to be served).
