Alkaline Diet Recipe #125: Coconut Quinoa and Sweet Potato Curry - This one is a WINNER! Quinoa was my personal big discovery last year – and now I can’t get enough! Quinoa is known for being a complete protein and perfect of course, for vegetarians/vegans. It is also a good source of the very alkaline mineral – magnesium. Combine this with Sweet potato and you have a nutrition-packed and delicious meal!
