I look for chubby sweet potatoes (with a relatively large diameter). Cut off enough of each end to provide a flat spot. Spiralize. I specify 2 large sweet potatoes for me and my husband as they shrink down as they roast. We never have leftovers, but if you do, you can certainly reheat them. They will, of course, lose the crispy texture.
Feel free to substitute full fat coconut milk. I typically use lite coconut milk in the interest of reducing calories and fat. ;-)
I specify massaman curry paste, but as I mentioned in the post, you can substitute one of the other Thai curry pastes.
Massaman Curry Paste or a homemade yellow curry paste.
