I complemented the orange color of the curried base of onions, potatoes, sweet potatoes and chard with a simple
blanket of purple sweet potatoes, lightly salted and piped into ribbons with a pastry bag and frosting tip.
Spread a
layer of purple sweet potato hummus over the crust and top it with roasted chickpeas, green peas, chives, cashew or any other vegan cheese, white sesame seeds, basil leaves...
The antioxidant
activity of purple sweet potatoes has been found to be 3 times higher than that of a certain variety of blueberries, but blueberries are considered extremely high in antioxidants (53).
