Low Fat Sweet Potato and Chickpea Patties

I came across this recipe that was given to me in 1995. I had forgotten about it so decided to make them last week to see how they tasted. I think that if you are diabetic, on a low fat diet or vegetarian then you will really enjoy them. They make 8 good sized patties so a serve is 2 patties. A serve is 1250 kj and has just 1.1g saturated fat.
I loved the mango yoghurt dressing that went with them.

INGREDIENTS:

500g sweet potato (orange)
1 can 420g of organic chickpeas
1/3 cup couscous
2 cloves garlic crushed(can used bottled)
1 lightly beaten egg
3/4 teaspoon garam masala
1 tablespoon olive oil
sea salt and freshly ground black pepper to taste
Dressing:
1/2 cup low fat greek style natural yoghurt
2 tablespoons good mango chutney (not hot)

METHOD:

Peel sweet potato and cut into rounds. Place in single layer on a microwave plate or dish, cover and cook on high for 4 - 5 minutes, depending on power. You may need to do in a couple of batches.
Place drained chickpeas and potatoes in a large bowl and mash through until almost smooth.
Add couscous, garlic, garam masala, egg, salt and pepper and mix through with your hands until well combined.
Place oil in a large non stick pan on medium heat. Wet your hands and mould 8 patties out of mixture. Drop in pan and cook for about 4 - 5 minutes on each side.
Mix yoghurt and chutney together in a small jug or bowl and serve together with a nice green salad.
