How did I not think of this earlier? So easy and so good.
Ok, grate up about 5 potatoes and put them in a big mixing bowl. Season with salt and pepper, then add about 1/2 tsp each of garlic, cumin, tumeric, onion powder, cayenne pepper or chili flakes, ginger, cinnamon, and garam masala. Crack an egg into the mixture, toss in 1/2 cup of peas, and mix well with hands. Cook in a well-oiled cast iron pan until golden browned on both sides.
Garnish with a little sour cream and chives. Mmmmmm.
