Sweet Potato Cakes

1 3/4 lbs sweets, peel & cut in lg pcs
2 tsp. butter or coconut oil
1 onion, halved and thinly sliced
2 tsp. tamari or soy sauce
1 clove garlic, minced
3/4 tsp. salt
pinch of red pepper flakes
1/2 c unbleached all purpose flour
1 egg, well whisked
yogurt sauce
1/2 cup greek yogurt
2 Tbsp. lemon juice
1 Tbsp. extra virgin olive oil
3 Tbsp. chopped cilantro or basil
pinch of salt and pepper

Steam the potatoes until tender. Cool. Warm the butter and saute the onion ~ 4 min. Cool. Blend the yogurt sauce ingredients in a food processor. Set aside. Transfer potatoes to a bowl and mix them with the tamari, garlic, salt, red pepper flakes and flour to combine. Add the onion and egg and mix. Add butter to a pan and warm over med high heat. Make small, two tbsn patties and drop them into the hot pan, pressing down to flatten. Cook until well browned on each side, about 7-8 minutes. Remove to a paper toweled lined plate. Serve with some lightly dressed greens and a generous portion of the sauce. These would be so wonderful with a poached egg on top.
