Preheat oven to 350 Fahrenheit degrees.
Now, you need to cook the potatoes! Chop into 1/2 inch cubes and bring them to a boil. Cook for about twenty or so minutes.
In a food processor or blender: place peppers, and half of the potatoes in and blend. Add margarine and cream cheese. Blend again, then place the rest of the potatoes in the processor/blender.
At this point, if I feel like the potatoes are not mixing to my liking, I will place some water (use judgment) in the mix then continue.
Scoop out potatoes in an oven safe dish. Place some extra vegan margarine (if you want) over the top. Chop the green onion and sprinkle over the potatoes for garnish. Place in oven until the onions are cooked a little.
I usually eat this with some avocado slices and salad.
Hope you enjoy!
