I used to always order yam fries with spicy dipping sauce at restaurants so it was perfect as my next experiment:
Simple, easy, cheap and delicious! This whole plate costed me less than $1, compared to ordering it at a restaurant for over $7 (don't forget tax + tip). Not to mention, a plate of sweet potato fries w/ spicy dipping sauce at a restaurant like White Spot contains approximately 7g protein, 82g carbs, and........55g fat!
Next time you crave yam fries, try this instead! :)
