Cook brown rice in advance and set aside to cool. This can be done well in advance and placed in the refrigerator until ready to make the patties.
In a large bowl, add brown rice, feta, cottage cheese, sweet potato, garlic, egg, plain flour & parsley. Season with salt & pepper.
Using damp hands, mix all the contents together until fully combined.
Create 16-18 patties with each being about 1/4 cup mixture.
Heat a thin layer of vegetable oil in a large frying pan over medium high heat.
Cook patties in batches until golden brown on each side. Approx 2-3 minutes each side depending on heat of the pan. Remove from pan and keep warm until ready to serve.
Serve patties on a bed of baby spinach and garnish with tomato chutney.
