Got this recipe from my friend Jordan. I think its good, but the meat-eating boyfriend gave it a solid "m'eh" as a meal, but loved it as a side! :)
4 medium pototoes, yukon gold in this case
Cube, cover just barely with water, and bring to a boil. Simmer for 1/2 hour or until soft. While the potatoes are cooking, in another sauce pan make a roux by combining over medium heat:
2 Tbsp flour
1/4 cup nutritional yeast
2 Tbsp margarine
Slowing whisk in 1 - 2 cups plain soymilk to make a white sauce. At this point I also added:
1 vegan boulion cube
Dash Salt and Pepper
1/2 tsp onion powder
When pototoes are soft mash with a fork leaving chunks then stir in the white sauce. Add soymilk to desired consistency if too thick.
Next time I think I will add carrots and saute some onions to go in it.
